I am slowly being driven insane by my three year old. When it is just the two of us, he is a lovely little guy. But he has an 11 month old sister, and I have a DH who is traveling for the next eight weeks.
He will NOT leave his sister alone. Just will not. Nothing I do helps. NOTHING. He is constantly touching, poking, pinching, tickling, laying on top of, hitting, kicking, and throwing toys at her. I have to intervene every 30 seconds, it seems. I am generally a patient person. I generally believe in letting kids work disagreements out for themselves. But he is so much bigger -- he outweighs her by at least 20 pounds -- and she cries and gets hurt when he bothers her, I can't just leave her to be hurt by him. I don't think his intention is to hurt her. There isn't anything wrong with him psychologically. He is nice to animals, loving to me, and many times is very loving to his sister. He sees me giving the baby pats and kisses and wants to give pats and kisses too, but they turn out to be smacks and head butts. He isn't able to judge how much he's hurting her.
I can't take this anymore. I am unable to do anything for more than 30 seconds, it seems. My mom was a screamer, and I do not want to scream and hit my kids. But I can now see where her anger came from -- the power of your preschooler to enrage you is amazing.
Pleeeeeeeease please help me! Give me some ideas. I am essentially going this alone for several months, with no family around, and I am at my wit's end.
