Thanks for your support guys, I really appreciate your comments.
Sushee - he may not know how to manipulate, but he's got pushing the boundaries down pat!! He knows that he's not allowed to do things - ie, put rocks into his mouth that he could potentially choke on, but he does it when we are watching him.. and makes a game out of it... so I've got a three strikes and you're out tactic going on there!!! It's hard with your first to know what they do understand and what they don't cos they sure seem to know the things that upset you the most!!!!!
He has been a bit better since waking up from the second half of his daily sleep, and DH will be home in an hour... that gives me something to look forward to!!!! haha!!!!

Thanks again guys
