Thanks so much all!
The last couple weeks I have let him CIO which hasn't been too bad. He sleeps at the bottom of the stairs in my rec room with another little girl (The biter) and I really didn't want her to wake up but after yesterday I realize she kinda sleeps like a rock. lol All my other LO's have gone to sleep much easier for me. He can CIO from now on. I was feeling a tad guilty but he still needs to learn our routine.

I def give time outs for hitting or anything like that. Usually I use the corner but I'm thinking of designating a chair from now on. I intervene a lot too but I can only do that for so long and then I have to make lunch, do potty time, etc…
She is a TERRIBLE teether and her mom and I have noticed that this is when her behaviour gets like this. There was a horrible day last week where it was so bad I ended up putting her in the highchair where she couldn't get out and hurt anyone. She spent about 1/2 hour there. I couldn't cook lunch otherwise. Her mom is great and we really work together on it. She also has a sibling arriving within the next month or so. Her "mine" world is about to come crashing down on her. I hope she isn't nasty to this baby.
