How did he/she develop into a tummy sleeper? LO just started rolling back to belly (but only in her crib). Initially she rolled while sleeping then freaked out. Now she rolls over within minutes of me putting her in the crib. She whines, but then will eventually fall asleep. But if she wakes during a sleep cycle transition she cries hysterically cause she can't get back on her back, so I have to go in and flip her.

If this happened to your LO, did he/she eventually become a tummy sleeper? Or did they just learn how to roll back to their back/side and sleep that way? I am wondering if LO wants to be a tummy sleeper because she continues to roll onto her tummy even if I just flipped her back onto her back? Or maybe it's just fun for her til she gets stuck and she actually does hate it.

ETA: She's 5 months old.
