My son is 15 months old, which I realize is still quite young. He does however have a great concept of the stuff he is not supposed to do. We've been battling with him standing on chairs, toy chests, the table. Pretty much everything he shouldn't stand on and could fall and get hurt from. He does know he shouldn't do this. He'll wait and watch us and the moment we look he'll crouch down. He knows what "on your bottom means" and will pretend he's going to do it but then shoot back up at the last second. We've implemented the pack and play as a time out area and he knows he doesn't like going in the pack and play the problem is it doesn't stop the standing on dangerous items. The moment I take him out of time out he runs right back to the bad thing and does it again. I'm very consistent about putting him back and offering a distraction the next time he comes out (though it doesnt work) but I'm getting frustrated at seeing absolutely no progress. Maybe I'm expecting too much, but I can't remove the object and I don't want to let him do something dangerous. I'm getting so frustrated! Any tips?
