I am realy worried that my dd is not sleeping enough and that it will affect her development. She only naps or half an hour to a max of 2 hours during the day and then sometimes only sleeps for 2 hours at night up to a maximum of 6 hours on a really good night. I know babies are supposed to get about 16 hours sleep per day and she never gets anywhere near this. When she gets her maximum amount of sleep she does seem happy and well rested amazingly but when she's not sleeping well she seems to be overtired and we have no idea how to get her to sleep when she's like that. She is co-sleeping with us (has been since birth as she refused to be put in a cot from night 1) and the only way she gets to sleep is either falling asleep after breast feeding on me or sometimes dh manages to rock her to sleep in his arms but she screams and screams for ages and often wakes as soon as he tries to put her down. She is also a very light sleeper, waking at the slightest noise.
