She sleeps sometimes just fine in her RNP, but ALOT of the time she wants to sleep on her tummy or side. She also can get squirmy and grunty inher sleep sometimes.ive tried swaddling her but she cries and wiggles! I have heard that its suppose to work to keep babies asleep, but she hates it. any suggestions on how to work his out?
