My husband and I are at a loss. My 5 year old daughter is a bright child, but her behavior is out of control. At this point it is becoming detrimental to our family and at times I worry about leaving her out of my sight when my younger daughter is around. She has tantrums that resemble that of a toddler, gets very angry, has outburst, says that she wants to kill her sister, that no one loves, mommy has ruined her life, etc. We often can't take her places because we know a tantrum will result. She will be starting kindergarten this year and we are very nervous! In the past we had to pick her up from preschool because of outburst and uncontrollable behavior. I have read books, spent lots of money on therapy and we don't know what to do. Love her so much but at times we feel like we can't handle her!
