I'd love to find one! My mum and nanny look after my little one so I can go to the gym weekly :) I think a Crossfit gym in Pontefract have mum classes but it's for a crossfit class rather than an actual gym x
Theres a small women's only place in Allerton Bywater that allow you to take your baby or child. I can't remember what it's called though. Other than that I think the ones with actual childcare are the far side of Leeds and also very expensive.
Following as this would be ideal for me!
