My 18 month old son has recently started slapping me and his nanny. He also has slapped other kids at the playground. he doesn't really seem angry or frustrated when he does it. It's almost like its out of curiosity. I have talked to him a lot about gentle touches, no hitting, etc. but it doesn't seem to sink in. We also tell him no when he does this and almost always give him a time out. But he'll just keep doing it if he's in the mood (which results in more time outs). I just bought the "Hands are Not for Hitting" book on amazon, so hopefully that will help. Any other ideas? Also assurances that my son will not grow up to be a sociopath are appreciated.
