If you've stood at the door wondering, you're not alone.
Babies can't tell you they're cold. The forecast says one thing, the wind says another, and everyone has an opinion: grandma, the internet, the parent at the park.
CozyBaby looks at today's weather and your baby's age, and gives you one simple answer. So you can stop second-guessing and get on with your morning.
“Is a onesie enough today?”
“Does she need a hat, or is that too much?”
“Will he be too warm in the pram?”
“Here's what Leo needs today.”
How it works
Tell us about your little one
Just their name and when they were born. Little bodies handle warmth differently as they grow.
We check the weather
Where you are right now, or any city you choose. We look at how it feels outside, not just the number.
You get today's outfit
Layer by layer, plus the little extras: a hat for the wind, a blanket for the pram, sun cream for bright days.
Small things that make a big difference
Made for their age
A newborn and a toddler need different things on the same day. The advice grows with them.
How it feels, not just the number
Wind, rain and strong sun all change what's comfortable, so they change the outfit too.
Wherever you are
Use your location, or check any city before a trip to grandma's.
It learns from you
Was today's outfit too warm or too cold? Tell us in one tap. Every answer helps us get it right for families like yours.
CozyBaby is a helping hand, not a rulebook. You know your baby best, so always trust your own judgment.
“Nobody warned me the hardest question of my day would be: is she cold? I overdressed her for the first month and checked the back of her neck every ten minutes. I made CozyBaby so other parents get one calm answer instead of ten open tabs. She's 3 now, and I still use it with her.”
Built on things you can trust
Forecasts from Apple Weather, updated through the day.
No ads, ever. Just the weather and what to wear.
Launching in Ireland, the UK, the US, Canada, Australia and Brazil.
