The 2yr old and 3.5yr old in my care have been at our gym's child care since they were 6wks old and 11mths old.
The elder child was in swimming lessons, so the younger brother needed to be in care for that hour and then they were both in for the hour afterwards whilst I did boot camp, or RPM or something.
All the staff in the local facilities here are fully certified and I find the gym carers fantastic.
As the children are only there for a short amount of time, the kids are given heaps of attention and activities.
The boys are both super excited to go see Meagan and Kylie
and I find them both super diligent about parents little *quirks* and requests.
