my 11 week old will not settle herself and can take upto an hour to go to sleep at night. She's definately not hungry because when I put her on my breast she comfort sucks for a couple of minutes and then falls asleep. If I then transfer her to her cot, she wakes up and screams. I have used a dummy but she often spits it out and if she does fall asleep with it, she wakes up often and we have to put it back in. I'm lucky if she sleeps for 3 hours at a time. She seems to need to suck all the time. Is she too young to leave her to cry for a bit? Help - I'm knackered!
