BIG little boy problems

Bentley potty trained recently. Since then he's decided he no longer has to listen to ANYTHING. He says I big boy I no care. We were up until 1130 last night fighting about bedtime. He's just so smart and needs something to mentally stimulate him. Any suggestions?

    Take something away that he really likes to play with until he realizes that he is not the boss. He is definitely testing his limits. If he get's upset and throws a fit then you tell him you will add another day without the toy unless he listens to you & his dad. Good luck.
