I have a daughter that turned 1 August 6th and I'm going thru custody with her Dad. She had her full weekend with him this past weekend. My daughter is very sweet and loving. At my house she is redirected when she gets into something she shouldn't or does something she shouldn't. Well she came back from her Dads acting awful. She was hitting, biting, yelling, and being really mean to her 5yr old brother. I don't know what to do. I feel as if she gets to do what she wants at his house with no correction. Anyone have any advise or have delt with this? I don't want to approach her dad and him get automatically defensive. I'm trying so hard to civilly co-parent, but I can't have my daughter coming back to my house acting like that.
