Clapset! Surely my husband feels the same lol!
Hubby takes both of them to the little gym on Sat morning (it was his idea not mine!). They start quite young, i think 6 months (but not sure for the saturday class). It is really good for both their relationship and the physical development of the kids.
But at this age, my husband was only taking them to the park talking about trees and other stuffs, then to the playgroung and then for a coffee (for him obviously). I mean that child is already doing a lot of groups, a nice one to one with dad is sufficient in my opinion.
