Pure speculation. It's been really odd that he's not been around other kids. Or anyone really apart from me! He's 18 months old and delighted that me and my boobs are at home with him 24/7. Must say, it was pretty sad today when we went for a walk and him and another toddler clocked each other, and me and the other parent both grabbed our kids and hurried them along. So, pure speculation, what's your guess? Nursery? Soft play? Etc. Bracing myself for a long slog of being my son's only interaction for a while!
