My daughter never sees her dad and I mad or upset or fighting, but my mom watches her during my overnight shift and I know she try's not to argue with her boyfriend while my baby is there. Unfortunately I'm going to need my mom to babysit in the mornings during school now and I don't know about her and her boyfriend are always fighting and it makes me nervous to leave my daughter there during the days. 😢 what would you ladies do in this situation???
