Our 6 week old daughter quite often at night after breastfeeding will fall off to sleep in a semi-conscious state, when I lay her down in her cot. However during the day she doesn't sleep much and only then if we cuddle her and rock her to sleep. If she isn't fully asleep when we put her down, she cries and we have to start all over again. Her grandma was with her for the 1st month and always held her to sleep and now she seems to have gotten used to that. What should we do to get her to sleep?
