MY kids were up all night. 
THAT must have been a nightmare. How many do you have?
2. They were just giggling and then would pretend to be asleep when I went in their room. I was exhausted today
That can be rough. I know I've dealt with that with my kids by giving them each 10 minutes of solo time before they go to bed. Allows them to get their energy out.
Ishould try that. They are 3 and 4
It should work! Let them pick what you do for the 10 minutes, then move to the other one. I've done puzzles, read books, and solve Rubix cubes with mine. Good luck!
Thanks
