Tumble tots was great fun. Three of my boys really enjoyed it. They loved the climbing and singing. I enjoyed the social side of it (sad I know, but was one of the things I looked forward to in the week). I think it made my boys more aware when climbing.
My youngest son really didn't enjoy it, but it could have been my influence as by the 4th one I'd gotten a bit bored with it and also had changed centres because we moved and I didn't know the mothers or the staff running it.
My DD loves it. Like Mumof4 says, it has made her much more aware when climbing. I feel much more confident that she won't hurt herself when playing now, as she thinks before launching herself off something.
I also like the way it is teaching her to take turns. It is definitely worth the money - my DD is missing it now it is the summer holidays, and I have to admit I'm looking forward to going back in September.
I am tempted to give it a go for the autumn term as an all-weather option for when it starts getting colder. I've looked at the courses run by different franchisees and the prices seem to be really variable depending on area though - £11 a session round here . We are in a nappy valley-type area but that's more than in some posher London postcodes (with presumably similar fees for hall hire etc) and nearly twice as much as some other suburbs! I hope it proves worth the money as it ticks all my other boxes (our local gym club is over-subscribed and a bit too far away).
My DD did it for 12months - just to build up her confidence really. When she started she wouldn't go on anything, and really didn't seem to enjoy it - I persevered, and after about 6 months (I can be quite patient!!!), she started to enjoy herself and go on everything. We stopped going after 12 months, as she's mastered all the equipment and her confifdence couldn't grow anymore there!!!! Worth it, but expensive.
