My 6 mo old can roll from back to tummy but not tummy to back. She sleeps in a Halo sleepsack (arms are left unswaddled) and has occasionally started to roll onto her belly at night time. She is waking up crying because she can't get back on her back. I would love tips or suggestions on what to do. I hate to make her cry it out since she hasn't mastered the skill to roll tummy to back, but I also don't want to be an enabler. I do practice rolling in both directions with her during the day but she has only rolled from tummy to back a few times and it's definitely not a mastered skill yet. Thanks!
