DS is 5 months and 1 week and is waking up EARLY and pretty unhappy, I think b/c he cannot get to his hands (he is used to sucking and gnawing on them all day). I need to unswaddle but he can only roll back to front and gets super upset when stuck on his tummy which is what he will do as soon as he is unswaddled. Should I try sleep suit? Or go right to sleep sack? If sleep sack do I just let him roll over and then fuss/cry until he falls asleep on tummy?
