Took my 18 month old today for a free trial of the toddler play & stay, it's great, my girl absolutely loved it, it's the happiest Ive seen her at any of the baby/toddler groups we've been to. She was smiling from beginning to end, so happy and free!!
There's lots of different games and music to dance to and you get to go round an obstacle course, parachute tunnels and such. The floor is springy so it made it even better haha. It's a really nice environment with lots of things to do.
The woman who runs/hosts it is really lovely, funny and energetic, it's a great group to take your toddler to, I am definitely coming back, I travelled half an hour and it's definitely worth it. Everyone should give it a go, especially as you can do a free trial.
