So my son is 6 months and weighs 24-25lb and is 28.5-29 inches long and has outgrown his sleep sacks and i had to stop swaddling him at 10 weeks because he started rolling from back to belly then. And i cannot find a sleep sack for older babies! He wears size 12-18 month and even some 24 month. Anybody know a place i can find some?? Thank you. I just dont feel comfortable giving him a blanket to sleep with yet and we always sleep with the air on so now i have to bundle him up in a long onesie and long pants and socks lol
