my daughter turned 3 last february and she does not sleep anymore. and sometimes she bothers me and the other kids who wants to sleep. I usually send her up in her room and give her like 5 books to read (max). i give her some coloring pages (5 max). Once she is done, I tell her to read her book to her dolls and show them her coloring pages. Then i click the door.
Some days, I can hear her talking loudly to her doll. POOR dollies!

but she is off my case.

with the boy, maybe you can find something he can do
