N.M.
I would recommend a Bumbo seat. My daughter LOVED it at that age. She too was very bored sitting in the bouncer and was always wanting something new. It is a foam type of seat that will hold the baby that can't sit upright. They even have a tray that fits on the seat so you can put a toy on it or even use it as a feeding seat when the time comes. I paid $39.00 for mine at Target and they come in a wide array of colors. It is a little costly but you can use it for up to 36 months. I hope this helps and good luck!
