@S. annalese awesome thank you so much! Gonna do that tomorrow!
You can enroll them in gymnastics, swim, rock climbing, martial arts. All of those things are community in nature. As in, ur child will bond with ppl at these classes they goto repeatedly and become a regular at. Social skills is only a concern if ur not taking your child outside ever. Also try co ops when they're older. Story time at library. Once school age, see if local school allows homeschoolers to participate in sports
I would google/call your local community center. Mine has weekly meet up and activities specifically for homeschooling students. Call local libraries because many have activities and educational days for homeschooling students.
