I just love Bumbos, especially with the tray. I can’t tell you how much I used them with my babies, from before they could sit up on their own (but could hold their heads up really well), and after. They would sit in them to play, to get some alert time off of the floor and their back, and even to eat their first bites of food. They’re small enough to be portable, so they were easy to take to other people’s homes or on the road. My babies loved them, and I loved them!
