Stop copying all the other kids? I mean I love that you're learning new things from them and will be smarter and develop more quickly being around all the other kids BUT that high pitch squeal when you want something that you learned from the 2 year old, not cool. And the slaps, scratches, biting and hair pulling is getting out of hand.
I guess this is where a parenting book would come in handy. I think I'll just google it.
Now, don't get me wrong, you're still the sweetest baby on earth and you think all these lovely new traits are funny. Even when you punched me in the nose yesterday and I swore it was going to bleed. For a one year old you've got some pack with that punch!
