answer:I’m not a therapists but I would suggest talking to the dad about her new issues and see if he is willing to sign off on her seeing a child therapists. It does seem that she is probably fearing abandonment but there can be more to this than that issue alone. For now I would just suggest that you always keep your promises. My husband was in the military and sometimes the kids took deployments pretty hard, but I found that by being consistent in everything I did, helped to reassure them that they could always count on me. She may be dealing with the feelings of rejection. I think when my brother and sister in law split up, that was my nephews feelings. Nothing much you can do there. I’m sure she feels loved and cared by you but if my friends are any indication, grandparents were not always a perfect solution. Children feel most secure in mom and dads affections when given. I have mostly adult friends and it seems that many hold resentment against their parents, despite other family members who try their best to make them feel secure. I’ve even seen a few posts here in fluther. Get her the professional help that she needs now before it becomes a larger issue of self loathing, and low self esteem.
