I would suggest start a blog for the kid and start putting everything in that and share the link with family and friends. Off course there may be websites. I'm not aware of it. But blogging is also a good idea.
Solid good idea to overcome ennui- boredom . ( btw today is celebration between your hub and you. Hap hap happy birthday to Him. Sure would make semiya palpayasam and order IBACO rich icecreams with generous nuts ) Thanks & regards.
You can post in Instagram , Facebook using a # wrt the work done by kids. There might be forums to post... Like teach learn web etc. I'm not sure
