On Friday we moved my 4 month old from a RNP to her crib since she was able to roll on her side in the RNP. After three nights she rolled on her side in the swaddle. So we switched her to the Merlin Sleep Suit. Well she can roll on her side in it also. It's 3am. What comes next? Do I wait to transition her out until she actually rolls over? Is it time for just PJs? Or a sleep sack? Any advice would be appreciated. She still startles herself awake, but she is also big 14+ lbs and has been rolling over since 3mo. Thanks!
