I would prefer using the pm for some other playgroups. My son went to Baby Gym and PArsons music in the pm. AM he went to N1.
Later for K1, I will bring him to other playgroups like Enopi, Cambridge English, painting, and one more sport. These have some new things to learn which are not taught in the KG curriculum.
I think that could better equip the child to be all rounded in preparation for P1 application.
