I can definitely see where it is her business. What goes on in the home where she lives affects her. If he brings the child home with him and then the mother takes issue with it the police could potentially become involved. If the police show up at the residence questioning who has what, she should be prepared for that or any similar contingency.
It would be better if the father posted but absent that and in light of the fact that OP says that father knows and encourages her participation its really not up to us to accuse her of being a busybody. Would be best for dad to post but if prefers OP to do so then who are we to criticize when we haven't all the facts?
Then who are we to answer when we haven't all the facts?
I'm not being facetious - but it goes both ways.
