G has been sleeping in a Love to Dream Swaddle Up since he was about 9wks old. We're at the point where he is about to outgrow the current size AND he is starting to roll. Last night, he managed to flip from back to front for the first time while sleeping. He woke me up crying. He STTN and has all but 1 night since he was 9wks old too. The question I have is, what should the next step be for what he sleeps in? I could buy the next phase of swaddle up (it's the same but has removable arms so you can remove one or both). Or I could get something else. I have some Aden and Anais wearable blankets that are hand me downs but they seem huge. Or is there something else, like zipadee zips? Any advice you have is welcome!
