Didsbury Nuffield Gym

I’m currently 20 weeks pregnant and working while my 2.5 year old is at nursery and can therefore go to the gym after work before I pick her up. However when I start maternity leave my current gym doesn’t have crèche. I’m considering Didsbury Nuffield (I can get 30% discount as I’m a teacher bringing my monthly fee £52). £25 more than I currently pay. My eldest will be 3 by the time I join so she will be an extra £16. But the site does say she gets access to a load of classes, the pool, arts and crafts, soft play and 2 hour a day free crèche. £7 for my baby and £4.5 an hour for crèche. I feel like we’re always paying to do things on the weekend so just really trying see if others find the additional for 3 year olds is worth it. How do others find this gym and what they offer kids there?
