We went to a local play place today. We'd been there once before and I took a photo of Matthew in this same box ( https://365project.org/sarahsthreads/365/2016-02-09 ) and I was pleased to see it was still there. :)
We'll probably come back a little more often now that he's older. It was a much more successful trip now that he's got some preschool and peer interaction experience under his belt.
