I'm sure this has been asked many, many times, but does anyone have any ideas as to how to help settle a baby for sleep? My DD is nearly 7 months old and up until a couple of weeks ago went to sleep no problem. We had moved her to her cot without a hitch, and had established what I thought was a good bedtime routine. I would put her down when she was sleepy and she would settled herself and fall asleep with hardly a murmur. For the past couple of weeks or so however, she has been crying, moaning, shuffling around her cot and it can take up to 2 hours for her to get to sleep. I've been putting her down as usual when she seems to be tired (rubbing eyes, quieting down, yawning) but when she gets in her cot and I or DH would leave the room, within 10 minutes the whinging will start and she will get progressively more worked up to the point of loud crying. At the moment, we've been going in, shushing and soothing her until she quietens down. If she doesn't stop crying we have been picking her up to calm her, then putting her down, but she'll often start crying again. By the time she does go to sleep she's exhausted because of all the effort it's taken!
Once she is asleep, she is usually fine and will sleep through until the morning. She is also fine for naps, and will settle herself without a problem, it just seems to be bed time that she's struggling with.
Can anybody help with advice or ideas? TIA
