I thought I was going crazy when I first had my son. I could not believe how difficult it was to get him to sleep! He is 15 months now and sleeps about 10 hours a night. He still wakes up once or twice for his bottle, but since we keep him in bed with us we can just reach over for his bottle on the night stand.
I REALLY don't like the idea of letting a baby "cry him/herself to sleep". I know several families who have done that and it seemed to work for them. But I felt very strongly from the beginning that I would not do that. Ty, my son, stays with grandma during the day and she lays on the bed and sings to him until he goes to sleep. She also leaves an air filter on for background noise so he doesn't hear their voices and wake up. I usually lay with him in the bed in a VERY dark room with the air filter going and just let him toss and turn for a while until he goes to sleep. Other nights, I stroll him around the house in his stroller with all the lights out (the darkness is key) until he goes to sleep. Once he is asleep, I wait a few minutes and then transfer him gently in to the bed. Some parents may think this is starting him on bad behaviors that will be difficult to break later, but I completely disagree. It is all about how you handle the situation. Creativity is so important with kids and helping them adjust to new things. Once he is old enough to communicate with me, I will start having him sleep in his own bed. I will likely go to his room with him, read a book, and lay with him until he goes to sleep. Then we can transition to having him go to bed on his own as he gets older. But if you make the transition fun, it makes it so much easier for kids. ... But to make a long story short, I recommend strolling her around in a very very dark part of the house. Good luck! I know how difficult it is!
