You need one of these

One of mine and my daughter's favorite purchases so far. Perfect for that in between holding head up and unassisted sitting stage, and it's super light so it can be moved from room to room with one hand. She would be content in this thing for over an hour if I let her. The saucer comes off, and it can be used as a feeding and booster seat strapped to a chair.
