A Baby Bouncer?

You can have an arch in your garden where you grow climbers, climbing plants that grow all around the arch. If you're doing certain yoga moves, you might have to arch your back as well. A baby bouncer is like a little deck chair that you would put the baby in and they can kind of go boing, boed, boing. And if you've got cruel siblings, then they might pull the child - I was a terrible big sister with my brother's doorway bounces.
