Not an ideal family dog as while he is usually devoted to his own children, he can easily mistake the intentions of their friends. Plus, in his clumsiness, he can knock over small children. With training and socialisation, the Rottweiler may be able to live with older sensible children.
While many dogs are traditionally thought of as being good with children, all dogs and children need to be taught to get on with and respect each other, and be safe together. Even so, dogs and young children should never be left alone together and adults should supervise all interactions between them.
