DS can sit with support...by me holding his back up or propped in the corner of the couch. I would like to find something made for babies to help him learn to sit up/to "hang out in" on his own without my constant attention. Whenever he's in it, I'd be in the same room, but at least I could get a second to flip through a magazine or something rather than keep setting him up cuz he's tipping over. Ok now for all my questions: do you think a bumbo is worth it? Or do you have something similar, but a different brand that you love? Is it even worth it to get one now since he should be sitting on his own soon...like is it worth the money just to get a month or 2 of use out of it? If you have one, do you have/use the tray on it? Thanks so much!
