I have 2 step children 7 and 5, and I have a toddler who is 18 months old. I'm at my witts end the 2 step children are constantly hurting my toddler. They do it when they think no one is looking or even sometimes while me and their dad are sat in the same room. They do not listen when told to stop it. What do I do? Do I ban them seeing my toddler? Because that is the only option I can Come up with as we have told them they won't be coming to our house if they carry on doing this, but they have to see their dad. We normally have them 3 nights a week but 3 nights of my little one getting hurt is really getting me down. I can't even go into the kitchen To make a drink, or even go to the toilet with out having to take the little one with me as as soon as I leave they will do something they aren't supposed to do. Its things like pushing the little one off her ride on car, getting her into a head lock and squeezing, hand around the throat, nipping, tripping up, squeezing head and face. Any advice much appreciated.
