I have an almost three year old who constantly wakes up throughout the night. For example, last night he woke up around 1:30am came in my room to see if he could sleep with me, I said no and asked him if he needed to go to the bathroom, then I took him back to his bed after going to the bathroom. He woke up two more times after that for no reason and then finally at 6am for milk and then for good at 7 am. What should I do about this? Should I try a sticker chart? Please help I believe he's not getting enough sleep and neither am I. This happens no matter what time he goes to sleep, early or late.
