Room is 24° tonight? You’ll know it’s the light sack with a short-sleeve bodysuit and nothing else.

The dressing check-in

Ten seconds after they settle. Smarter every night.

Feel the chest, tap how it felt. Repeated patterns help TinyLayers personalize the base layer over time.

How it works

One practical question. A calm answer in three steps.

TinyLayers is a baby outfit guide for real nights and real outings — built for tired parents who need plain English, not another chart to memorise.
01
Choose the situation
Sleep, nap, going out, stroller, carrier, or car seat — pick the moment you are dressing for.
02
Add age and temperature
Room temperature for sleep and naps. Outdoor conditions for outings. Age adjusts the recommendation.
03
Get a calm answer
Plain-English layers first, TOG as a helper second. Then confirm with the chest check after settling.
Six modes

Guidance for the moments that keep you guessing.

01
Sleep
Room temperature in, plain-English layers and TOG out — so you can close the nursery door calm.
02
Naps
Daytime settles need the same care as night. A nap outfit that matches the room you are actually in.
03
Going out
Outdoor weather for walks and errands, without using the forecast to guess how warm the nursery is.
04
Stroller
Layering for fresh-air rides — warm enough outside, without overheating under blankets and hoods.
05
Carrier
Close-contact warmth is different. TinyLayers accounts for shared body heat when baby is on you.
06
Car seat
Thin layers under the harness. No bulky coats or snowsuits under car-seat straps.

TinyLayers is built on common TOG sleepwear guidance and safe-sleep recommendations from trusted public health sources, including AAP guidance. It provides general dressing guidance only and does not replace medical advice.

Questions, answered

What does TinyLayers actually do?

You tell it the room temperature or the outdoor conditions, your baby's age, and the situation. It returns one plain-English outfit — layers first, TOG as a helper — plus the chest check that confirms it.

Is TinyLayers free?

TinyLayers requires an account and an active plan. Monthly is $4.49, with a 7-day introductory trial when offered by the App Store and you are eligible. Lifetime is $14.99 with no trial. Prices vary by region. Cancel a subscription in App Store settings before renewal.

What is TOG?

TOG measures how much warmth a sleep sack traps. 0.5 is summer-light, 1.0 is the everyday middle, 2.5 is for cold rooms. TinyLayers gives you layers first and treats TOG as the label on the sack you already own.

What ages is it for?

Newborn through toddler. Age helps tailor the guidance. Never use hats or loose blankets for indoor sleep. Stop swaddling once signs of rolling begin. For premature babies or medical concerns, follow clinician guidance.

Does it track my location?

Only if you turn on outdoor weather for outings, and only to fetch conditions. Location is used to request weather conditions. Sleep guidance uses the room temperature you provide. See our Privacy Policy for details.

Is this medical advice?

No. TinyLayers gives general dressing guidance built on published safe-sleep recommendations. Always check with your health visitor or paediatrician for your child's specific needs.

Close the nursery door calm tonight.
