My DD is 7 months old tomorrow & she co sleeps with me as she refuses to fall asleep alone and as soon as I move her into the cot she screams. I really struggle to settle her for a nap and when she finally falls asleep it's not for long. I would say she has 2 hours in total naps throughout the day but she is sleeping 12 hours at night. She is also a very light sleeper so I can't get anything done in the time she's asleep because she wakes up to even the slightest bit of noise. Is This normal ? has anyone had the same experience?
