LO still wears a sleep sack because I am not comfortable with blankets yet (she is 6 months), but all of her little friends who are the same age use blankets. I am hoping I can find some larger ones used so I don't have to pay so much for one, and that way we can continue to use one for a while. Everyone I know thinks it's weird she still doesn't use blankets...

How long did you/will you use the sleep sack for?
