Toddlers run warm and move a lot, so a touch lighter is fine.
On warm days a toddler moves to a T-shirt and shorts a little sooner than a baby.
For sleep, the app dresses a toddler as if the room were a little warmer, so the lighter sack comes a degree earlier.
No hats or loose blankets for sleep. Check the neck — warm but not sweaty means just right.
