My brothers kids mom doesn't watch their son. Like she stays in the bedroom sleeping all day until 5pm then she stays in the room all night long. It doesn't make any sense. He asked if I would watch his kid while he went somewhere. I nodded my head but I was about to tell him where the hell is his mom at lol like dang. I watch my kid all day long she needs to watch hers and stop expecting people to do it for her. He knew my nod meant no so he took him with him lmao idc. He needs to make his bm be a damn mother and stop being so lazy. A real mother gonna be up tending to her kids every need but she doesn't do crap
