hi share lang pod ko...my 22 months old son knows the pc too but not the games. ofw iya papa so we communicate through internet, when he sees the pc, mo ingon dayun xa ug daddy...kung magduwa sad ko ug games dili nako xa pakit-on, rather, educational na shows sa youtube like the giggle bellies, lingaw kaau xa ani...still the best way I think is moderation, let your child explore other than pc games, I would take him for a walk in the afternoon to watch basketball games or soccer, xa pa ang mo ingon ug suroy...mas lingaw jud ingon ana kay ma amaze pa ka, kay sa maglingkod mo duha atbang sa pc hehehehhe.......
