Is 3 months too old for this? DH and I had a big ol fight this morning bc DS woke up w/scratches all over his face (sorry I can't seem to keep up w/his fast growing fingernails) We have a couple of pjs that have the flap on the end of the sleeve...he loves to suck his hands but will chew on the sleeves just the same...but I feel like he is too big for this, any opinions?
