Without knowing the entire story bio-mom may have a legit reason for keeping her son away Halloween You can’t scare me I work at Walgreens I’ve seen it all shirt. Maybe she is afraid for her son’s life? Or maybe she is being difficult. I don’t know so I really cannot make a judgment/give advice based on just your side. Hopefully whatever the case is everything turns out ok all around especially for the child. If it just started…have the patience for a while. I am bipolar. Going from diagnosis to meds. I was a wreck. I couldn’t think clearly. Give her a chance to get it together. Children are a lot more resilient than we adults. Remind them of the bonds they share and why. She needs a chance to get better…not forever but at least a few months?
