My 5mo little girl naps in her cot and still sleeps in her next to me crib. She loves to roll back to front but struggles to roll back again. Every time I put her in her cot, she rolls onto her tummy and then gets hysterical until I go in and roll her back over. I am flipping her back over anything you to 20 times per nap! This is obviously really frustrating and means it can take ages to get her to go to sleep. Any advice? TIA xx
