I went thru the same thing with my son...Even tho it is very annoying when you are tired and want to get some sleep and you have to keep getting up...i just kept putting him back in his bed everytime over and over again...every night for like 1 week.....untill he got the point.....i know its not alot of info...but it worked i would feel so bad because he would cry and cry...but i stayed firm and said no bedtime....when he would kick the wall and stuff i would just ignore him until he knew i was not getting up again.....and when he kept getting up to go to the "bathroom" i would just tell him if you keep getting up i will close the door or turn off the lights if he got up again i would turn them lights off or close the door for like a min.....he would see that im not playing games and he would stay put..it sounds kinda mean but i worked he sleeps in his room now every night...hope this info is a little helpful
