QuoteShould I just go and get DD, and tell grandma tough, she can come back when BM is better?
That's EXACTLY what I'd do. Or better, I'd wait till the next visitation and then just keep her till BM is able to care for her. Cripes, it's insane how BM's will go to any length to have someone other than dad care for their child when she's not able. When our Bm was in the hospital with pregnancy complications, SD stayed with grandma. Recently when SD had her wisdom teeth removed, SD stayed with grandma, even though dad had the entire week off of work. It's crazy!
That is your daughter and even without FROR or joint custody, I'd have her in my care if the other parent wasn't available if it was me.
