i currently live in nebraska. my exhusband and i were divorced in polk county iowa. we have joint legal custody of our 3 children ages 6 and 8, but i am the custodial parent (they live with me). during their visits with their father, they have been injured. he is not intentionally injuring the children, but i feel that he makes some bad decisions when it comes to their physical well being. i have spoken to child protective services in iowa twice now. the first time, they said that he was not a threat to their well being and he should continue to see the children. this time, they are telling me to get a lawyer and change the visitation that he gets to supervised visits. i spoke to a lawyer who said basically that i have a flimsy case because i don't have a lot of proof or any witnesses. how can i be sure that child protective services won't come back on me and say that i didn't protect my kids? i feel awful with the though that i could be taking my kids away from their father but at the same time i know that what he does/doesn't do isn't right. where do i start?
