@Carly thank you! Have you been there before? It’s about 20 min from me and not sure whether worth the drive!
I used to go and did a fitness program with them for 3 months, that was a while ago now. I've never used the crèche but the children always looked like they were having a good time. I'm sure you could have a look round and see what you think.
There's a ladies only gym in Kingswood which has a crèche, it's £55 a month for unlimited crèche and classes. ITS fitness.
