I have heard lots about this but wasn't sure if it was true. Both my children have been such good sleepers. Grace is a little more sensitive so we have her room totally blacked out. But the last week she has been waking early and tonight has been awake since midnight to now 4 am. I don't want to start bad habits but she was asking for food. No wonder after being awake that amount of time. Any one else had this? Tips? Howling did it last? X
