My fiance's mom watches B everday while we're at work. Along with B, she watches our nephew, Kaleb (almost 2), and our niece, Dina (7 months). Well, recently, Kaleb has been a tad more wild than usual, and poor Grandma is about at her wits end. She just recently began watching B, and we think that poor Kaleb is a little bit jealous now that he is having to share some of the lime light with his two new cousins. He's not responding when Grandma is telling him "no" or "stop," and he has recently began shouting "no" himself and threatening to hit Grandma. I know he's reaching those "Terrible Twos" that we all hear about, but what can be done?!
