Sandy is constantly running over Stevie (quite litterally). She is about 10 times more mobile than he is and no matter where I put him to play she will get over to him and take his toys, his binky, pull his bib off, and often push or pull him down. Of course this ends in Stevie screaming and not wanting anything but being held. I've tried giving her something else to play with or just giving her what she took and giving something else to Stevie. Unfortunately that doesn't work because she just takes that away from him too. Between this and her constant temper tantrums and getting into things I don't know what to do with her.

How old is she?

14 months.
