I have a 3 year old who is increasingly jealous of his 1 year old sister. It seems that all day long he tries to push, squeeze, or hurt her in some way. He has recently become more defiant. It's very hard to have another of his friends over as he often pushes, does things they don't like and such and does not listen when corrected. Anyone has good advice or similar experiences? I'm losing my patience with him.
