Hi, my questions sort of relates to this thread so I'll post here! I have 3 children around 20 months old and one older sibling who will be 4 in April. My kids here learn through play mostly but I was wondering if I should do more with the oldest child? He can count objects up 20, use glue to assemble crafts without help, recognize and write his name, sometimes hold a pencil properly etc. Honestly, he just wants to run around with the little ones and has no interest in sitting still for more than 2 minutes so I have worked these things into play! His parents seem thrilled that he can do so much more than before so I'm really just wondering for future reference if anyone thinks only being around younger children would hold someone back at all?
