Stage 1: Discovery & Research

1.1 Problem Statement

The Problem I Wanted to Solve

The Problem: Parents who sleep-train their children (ages 0–3 years) struggle to dress them properly for nighttime sleep. The room temperature changes overnight, they can't go in to check without waking the baby, and the clothing rules are different depending on the child's age. This gets even harder when you have more than one child who each need different outfits for the same room temperature. Getting it wrong means the child is either too hot (which is a known risk factor for SIDS) or too cold (which means they wake up and the sleep training breaks down).

Why This Problem Matters

This isn't just about comfort — it's about baby safety. Overheating is one of the known risk factors for Sudden Infant Death Syndrome (SIDS), and underdressing means the baby wakes up cold at 3am, breaking the sleep routine that took weeks to build.

The Core Tension

Here's what makes this problem tricky: I dress my child at 7pm, but the coldest point of the night is around 3–4am. The room temperature can drop by 3–5°C overnight depending on the weather, whether the heater is on, and how well the house is insulated. As a parent who sleep-trained my child, I can't just pop in at midnight to add a layer — that defeats the whole purpose.

1.2 User Personas

Who I'm Building For

Through my own experience and conversations with other parents, I identified three types of parents who face this problem. These aren't made up — they're based on real people in my life and in the parenting communities I'm part of.

👩🏾‍🍼

Naledi M.

"I just want to know my child is comfortable without going in there."

Profile: First-time mom, 29. Just sleep-trained her 5-month-old after weeks of effort. Works as a teacher in Sandton. Uses her phone for everything — weather apps, baby tracking, and sleep training content.
Core Pain: Terrified of getting it wrong. She read that overheating is a SIDS risk factor and now second-guesses every outfit choice at bedtime. Doesn't have a nursery thermometer — just checks the weather app and hopes for the best.
What She Needs: A fast, confident answer at 18:45 — just before putting baby down — that accounts for what the room will feel like all night, not just right now. She wants it personalised to her child's age. And she wants to stop worrying once the door closes.

👩‍👧‍👦

Lindiwe K.

"My newborn needs a swaddle, my toddler needs different clothing — and it's the same room temperature."

Profile: Second-time mom, 34. Has a 3-month-old and a 2-year-old sharing a room in Pretoria. Works part-time from home. Experienced with baby products but overwhelmed by managing two different dressing strategies every night.
Core Pain: The rules are different for each child. Her newborn needs a swaddle; her toddler needs different clothing. She knows the guidelines but can't keep them straight at 19:00 when both kids are fussing. She's done the research — she just needs the mental load lifted.
What She Needs: Multi-child support — one app that gives her a recommendation for each child, based on the same room temperature but adjusted for each child's age. She doesn't want to look things up; she wants to be told.

👨‍🍼

Thabo J.

"My wife usually handles bedtime. When it's my turn, I have no idea what to put on the baby."

Profile: First-time dad, 31. Software developer in Johannesburg. Wants to share bedtime duties equally but feels lost on the clothing side. His wife has the intuition; he wants the data.
Core Pain: Doesn't know what a TOG rating is. Doesn't want to Google it at 19:00. Just wants a clear, visual answer: "Put this on the baby. Done." He's comfortable with apps and would trust a well-designed recommendation over his own guesswork.
What He Needs: A simple interface that gives him confidence without requiring any prior knowledge. Layer-by-layer visual instructions, not just a TOG number or a text-heavy chart.

Shared Pain Points

🌡️ Temperature Guesswork

"It's warm now at 7pm but I know it'll get cold by 2am. Do I dress for now or for later?"

🚪 Can't Check Without Waking

"If I open the door to feel the room, the light or noise might wake the baby and undo weeks of sleep training."

👶 Age-Specific Confusion

"My newborn needs different clothing than my toddler... the rules keep changing and I can't keep track."

😰 Safety Anxiety

"I read that overheating is a SIDS risk and now I second-guess every outfit choice. Am I overthinking this?"

1.3 User Research

How I Researched This

It Started as a Personal Problem

I didn't start this as a product exercise. I started it because I was the parent standing in front of the wardrobe at 18:45, holding a fussy baby, trying to figure out whether a 1.0 TOG or 2.5 TOG sleep sack was right for the night. It was autumn in Johannesburg — warm at bedtime, cold by 3am — and I never felt confident in my choice.

So I asked my "Clueless Parent" WhatsApp group — a group of parents I'd been texting with since pregnancy. Turns out, every single one of them had the same problem. Some were Googling TOG charts every night. Others were just guessing. One parent admitted they'd been keeping their baby in the same sleep sack all year because they didn't know how to adjust for the seasons.

That WhatsApp conversation became my first piece of research. The parents in that group became my first testers, my first feedback loop, and the reason I knew this problem was real before I wrote a single line of code.

Where I Did My Research

Beyond my personal experience, I used a combination of: WhatsApp group discussions with real parents in my network (the "Clueless Parent" group — 12 active members), online parenting communities, and reviews of existing products to understand what parents need and where current solutions fall short.

Online communities I read through: Reddit r/sleeptrain · Reddit r/beyondthebump · BabyCenter Community Forums

What I Heard from Parents

"I check the weather app, then Google a TOG chart, then try to do maths at 7pm when I'm exhausted." — The current process is broken across 3+ steps and sources.
"My house is old and draughty. The thermostat says 21°C but my child's room is definitely colder." — The temperature reading for the whole house doesn't match the nursery.
"I bought TOG 1.0 and 2.5 sleep sacks but I never know which to grab on in-between nights." — Parents own the right gear but don't know when to use which one.
"It's different for my newborn vs my toddler and nobody explains that clearly." — Age-specific guidance is scattered across different blogs, not in one place.
"I wish something just told me: tonight, use the 2.5 TOG sleep sack with a long-sleeve onesie." — Parents want a specific answer — not a chart they have to interpret.

The Bedtime Decision Loop

Through my research, I noticed the same stressful pattern coming up again and again — a 5-minute window (usually around 18:45–18:55) where a parent has to:

Check the current room temperature (if they even have a thermometer)
Open a weather app to guess how cold it'll get tonight
Try to figure out how the outside weather affects the room
Google or remember the TOG chart for their child's age
For parents with more than one child — repeat this for each child
Make a clothing decision while simultaneously managing the bedtime routine

This takes 3–5 minutes of mental energy at the worst possible time — when the parent is tired and the child is fussy. My app collapses all of this into one step: open app → see recommendation → dress your child → done.

1.4 Competitive Analysis

What I Found Already Exists (and What's Missing)

I looked at everything parents currently use to solve this problem — devices, websites, blogs, and the "DIY" approach most parents fall back on:

Solution	Type	What It Does	What's Missing
Sleep Like Goldilocks	Physical device ~R700	Room thermometer + nightlight that shows a TOG recommendation on screen based on predicted overnight temperature	Needs a physical device, expensive, hard to get in SA, doesn't adjust for child's age
Tommee Tippee GroEgg	Physical device ~R400	Colour-changing thermometer (blue = cold, red = hot, yellow = safe)	Only shows room temperature — no clothing recommendation, no overnight forecast
ergoPouch TOG Chart	Website Free	A visual chart mapping room temperature to clothing + TOG rating	Static — I have to look it up manually. It doesn't know my room temp or my child's age. Only promotes their own brand.
Taking Cara Babies Blog	Blog Free	General advice on how to dress your child for sleep	Generic tips, not personalised. No real-time temperature input.
Weather app + Google	DIY Free	Parent checks weather forecast, Googles TOG chart, makes own decision	Fragmented, time-consuming, requires mental maths. This is what most parents — including me — were doing.
Snug Tonight (mine) 🌙	Mobile app Free for 1 child	Set up a child profile, get personalised outfit recommendations based on overnight weather and child's age, track wardrobe and laundry, log morning feedback and see patterns. Adding more children requires a Premium subscription.	This is the gap I'm filling → Personalised, age-aware, overnight forecast, no hardware needed. Premium unlocks multi-child support.

Sources: sleeplikegoldilocks.com · ergoPouch TOG Guide · Taking Cara Babies

My Advantage: Snug Tonight is the only no-hardware solution that gives personalised overnight clothing recommendations by age. It's free for 1 child, and parents who need multi-child support can upgrade to a Premium subscription. The closest competitor (Sleep Like Goldilocks) needs a physical device that costs around R700, doesn't adjust for the child's age, and can't handle multiple children.

1.5 Opportunity Sizing

How Big Is This Problem?

I wanted to understand whether enough parents face this problem to make the app worthwhile — not just for me, but as a product that could genuinely help people at scale.

All Parents of Children 0–3 (English-speaking markets)

Parents in South Africa, UK, US, Australia, Canada, and similar markets

~30M households

Parents Who Sleep-Train & Use Apps

Parents who actively use phone apps for parenting guidance and have sleep-trained their baby

~8M households

Parents I Can Realistically Reach

Through parenting communities, WhatsApp groups, and word of mouth

~200K users (Year 1)

Based on: CDC US Birth Statistics · Stats SA · Huckleberry app has 1M+ downloads on Google Play, showing parent willingness to use sleep-related apps.

Why I Believe These Numbers

Roughly 3.6 million children are born in the US each year alone, with similar numbers across the UK, Australia, Canada, and South Africa. The 0–3 age window means about 10–11 million US households are in my target group at any time. Research suggests 50–70% of parents in these markets try some form of sleep training, and this audience is very active on apps (Huckleberry has over 1 million downloads). My estimate of 200K reachable users in Year 1 is conservative — it assumes organic word-of-mouth through parenting groups with no paid advertising.

This Is a Daily-Use Product

This isn't a one-time lookup. Parents face this decision every single night for roughly 1,000 nights (from birth to about age 3). That kind of daily use is important — it means the app becomes part of the bedtime routine, not something people use once and forget about.

1.6 Key Takeaways

What My Research Told Me to Build

From everything I learned, five principles came out that guided every decision from here:

#	Principle	Why
1	Plan for the whole night — recommend based on the overnight low, not just the current temperature	The room at 7pm is not the same as the room at 3am. The overnight forecast matters more than the current reading.
2	Adjust for the child's age — different rules for newborns, infants, and toddlers	Swaddle rules, TOG ranges, and blanket safety all change as the baby grows.
3	Give the answer in 10 seconds — no searching, no scrolling	Parents are exhausted at bedtime. Every extra step is a failure.
4	Be specific — say "use the 2.5 TOG sleep sack + long-sleeve onesie", not "dress warmly"	Parents don't want charts to interpret. They want a specific answer they can act on immediately.
5	Ground it in safety — follow paediatric guidelines and flag overheating risk	This is a baby safety product. Parents need to trust it, and trust comes from following real medical guidance.

Safety guidelines referenced: The Lullaby Trust (UK) · Red Nose (Australia) · American Academy of Pediatrics — Safe Sleep

Decision: Move to Stage 2. My research confirmed this is a real, frequent, stressful problem with no adequate free solution. The gap in the market is clear, the audience is large enough, and the need is well-defined. I had enough confidence to move forward.
