what does baby wear to bed?

Ky

my almost 6 month old just moved into his crib last night. what do your babies wear to bed? he used to sleep with a blanket in his rock n play where be slept the last 6 months. do your babies sleep with a sleep sack? if so what do you put under it? my son was sleeping with cotton footie pajamas and a light fleece blanket. now that the weather is warmer our house is 70 degrees when he goes down but gets down to 65 through the night.
