I know there's a tube or something out there that wraps all the way around the baby when they are learning to sit up. I don't know the same however, so have no way of finding it. I read it in someone's post here, but now I can't find it. I need something that goes all the way around her because she tips from side to side. I have a boppy, but it's not steady enough, and she manages to tip thru the opening. Any help would be appreciated. Also, I have the Bumbo chair, but she doesn't care for it.
