Thanks for all of the replies!
a quick update.
We've found a kid locally who is a good match for outdoors/playground time. It's not a perfect match, but I took your advice and found a 4 yo for Nick to play with. The library trip wasn't so good as Nick's skills are more advanced and he became frustrated with his friend, BUT the outdoors playtimes are going well, and though Nick is still physically more agile/advanced they play really well together!
Good luck to all who have kids starting preschool in the fall. I need more vibes that perhaps we'll find a real peer in the classroom! (A girl's gotta dream, you know?)
