Well we did it! And it wasn't as scary as I thought it would be, haha!
The majority of kids were around 13 months so Andrew was a bit young (not the youngest) but he still seemed to enjoy it! He stood with the help of a prop, played with some toys, rode (and was pushed around in) a little fire truck, swang/ giggled as he flew through the air, lounged in the ball pit and had a blast in a bouncer!
Here are some photos:
