I thought the bumbo seat was very useful. It's very portable. When we would go places I would bring it and put my daughter in it on the floor when she couldn't sit up by herself. My sister put hers in her sons crib (although I don't know if it is reccomended)and let her son stare at his mobile and the toys in his crib. She would stay in there with him and clean or fold clothes. Once my daughter could move around more she didn't want to be in there, I don't think she liked being confined. She didn't like the jumperoo either. She did like the little einsteins excersaucer though. Hope this didn't confuse you more. The bumbo seat is different from excersaucers.
