How do you handle two kids??I thought it would be easy, but my older child is terribly demanding of attention, and the girl is already capricious, she barely sleeps, and doesn't eat.From neurology, everything seems normal, I don't know why she's like this.I go crazy with them both, when the boy is home from kindergarten - it's the end of the world for me.
