How's your DD going hon? I realised I didn't get back to you. I can't exactly remember when we weaned DD2 off her sleepy wings but it must have been around the 8 month mark I think so yeah, your DD might be a bit past them. Some babies do use them past this age though and even when rolling as they are stretchy so they *should* be able to get their upper body up off the mattress if need be.
