My children's father and I have 50/50 time and joint custody. He has moved them into his girlfriend's grandmother's 2 bedroom. My children do not have a room, sleep on couches, say he doesn't bathe them (they are 5 and 6, and he has them for up to 5 days at a time), he gices them wedgies, and when they "play fight" he hits them hard enough to knock the breath out of them. I can't affors an attorney to change the custody/parenting time arrangement. Would it be in the best interest of my children to call cps? And would that even help me?
