anyone has problem with toddler's sleep? my son 3 y.o. doesn't want to sleep. Make me awake until 3 am or 4 am almost every day!

I asked my girl to keep all the books after bes time stories. Toy are all kept outside and not in the room. Room is just a bed and i usually closed the door fully when i put her to bed so that she will not open and run outside to get her toys. Mayb u can try this
