I've had to start putting the kids further apart when they are on the floor playing because Timothy always takes whatever Cameron is playing with. She's starting to notice and cries when he takes something out her hand. I thought keeping Timothy out of reach of her would do the trick...but then I hear her cry and look over...he has somehow scooched himself close to her again! And if he can't have the toy, he'll just take her!! Lots of fingers in the eyes and hair pulling going on. They think it's funny...for now.
