sleeping through the night

Dont you worry lady, elderly people say that young kids remember their mother while sleeping n they wake up all of a sudden. It might be that at that time they are hungry.. Coz normally it takes 3 hrs for the food to get digested, either liquid or solid. So there is the nightfeeding and the child sleeps again. As they grow older and start taking more solid food they will start sleeping in a much better way. My mom always tells that I used to disturb her a lot by waking up in the middle of the night.. No nightmares here.. Its just that the child wants the mother to be with them.
