has your daughter seen a counsellor? this might be a good idea as this behaviour does not sound normal at all, perhaps this is her way of expressing her feelings about her father not being there, perhaps she is scared for him or misses him very much and this is the only way she knows how to articulate her feelings. Talking to an objective observer who can reassure her may be helpful. good luck!
She has seen a counselor in the past, and is diagnosed with ADHD (severe) due to being a preemie. I have a psychiatric appointment on july 25th, so hopefully we can get a referral to a regular counselor at that time.
