Just that really. DC (4) does no activities, I ask regularly.. "would you like to go to swimming lessons, gymnastics, dancing, football?" etc etc. I've given lots of options and just not interested, is extremely "shy" (hate using that word), and always wary of new situations but I just feel guilty DC doesn't do any hobbies, goes to nursery and interacts well with children there so no concerns with that.
I just accept the answer but I often wonder should I almost "force" the issue to put out of comfort zone as I know they would enjoy once over the initial joining stage or should I continue to just leave it.
