Thanks, MadonnaM... Yes he goes to pre-school its a small home based facility so they are like family now.Kyle for the most part is well behaved there, they are very used to his naptime meltdown which is just a few minutes of crying when he's tired, so i wouldn't say his tantrums interfere the kids love going they even ask to see Miss Sandy on the weekends, but he did hit himself today which he's never done there before, i called a local counselor who said he prob just isn't sure how to handle stress and she suggested that his father and I do a shorter schedule like 3 days @ dads and 4 days with me ect.. and thank goodness his dad agreed! So I'm hoping that works?
I think I would talk to his father again about letting him call you everyday to see if the behavior improves. I think you are right and he does not know how to express his anger and frustration with the changes in his life. Does he go to preschool? If so how is his behavior in school? I would not be overly concerned yet. If this behavior interferes with school or daycare and he becomes uncontrolable then you might want to seek a professional.
