My daughter who has CF is a light sleeper but usually slept really well at night, unless she was sick(like any other child) My son(no CF) as a baby would wake and want to nurse back to sleep , once maybe twice a night(can't remember). Do you go in the room right away when your baby cries? Sometimes they cry for a few minutes and then fall back asleep. With my son, I would bring him in the bed with me(I know lots don't agree with this) Nurse him back to sleep then carry him back to his crib. Occasionally he would sleep in the bed with us(I really needed the sleep). It was just for a very short time(in the scheme of things), he weaned at 15 months. When my son was more active, running and all that he slept better. My daughter(with CF) weaned when she was 3 1/2 years, she never had sleep problems. Every baby is different. But you NEED your sleep. Is your baby taking too many naps? If my son would get a nap too close to bedtime, I knew he'ld be up at night. HTH
