I feel your pain! My almost 3 year old (July) would wake up throughout the night, sometimes it was just once to use the bathroom, other times he would wake up 3 or 4 times a night. If I tucked him back in he would go right back to sleep...but the waking up was making be exhausted! He has been much better lately, we have been discussing how he needs to sleep like a good boy and that when he wakes up all the time it is making mommy really tired. Also when I put him to bed at night, I try to go over all the things he would wake up for (you are safe in your bed, mommy is right next door, there are no such things are monsters, that if something wakes him up he needs to turn his music box on and go back to sleep, then I tell him give me one more giant hug and I'll see him in the morning). Also when he would sleep good, I would talk to him about what a good job he did sleeping the next morning. We do have a gate at his door because I know he would be the kid that crawled into bed with us all the time if we didn't!
