Is Lifetime/Gym child care a viable option?

I’ve been a member of Lifetime for a while and hear about their child care services for parents to workout without worry. I am curious to hear from parents (or someone you know) that have used gym child care service about their experience. Specially how it works for little babies, as I have a 4 month old.

Is the child care trustworthy? Are you able to workout in peace for 45-90 mins? How far in advance to you have to plan out your workout and register?
