My Almost 2yr Old Won't sleep straight through the night...?

First off he needs his own room..When he wakes up he sees mommy and daddy there and that means someone to play with. If there isnt room for him to have his own room then thats fine also but when he ask's for stuff tell him no and that he needs to lay down and go back to sleep. It will be ruff the first couple of nights/week. If he can have his own room and a big boy bed just keep putting him back in his bed. Watch supernanny and you'll see a good way of doing. My daughter is 20 months and is in a crib and some nights she wakes up and if i know nothing is wrong i jut let her cry it out and scream and shoot...
