Hello A., I have a 3 year old son as well that I want to get involved. If you are near Holt, try this site: https://www.gsinet.org/partners/Holt/default.asp
Here is the "Holt Community Education" number: ###-###-####.
I wanted to get my son into soccer but they started a day we couldn't be there. I did get my daughter into swimming for $36 for 6 weeks, one day a week. It's very good for her. Aqua Tots is for 3 to 5 year olds. I think they have more in a few months. I also signed up my daughter for skating at Edru, I believe it was $22 for her to skate and not me, for 6 weeks. You have to pay double to skate too. I will be trying these things with my son next year. The Holt Community Education office is in the Holt High School on Holt Rd. If you call them, just ask for a list of Enrichment activities or the Ram's Magazine. Good luck! Hope it goes well. ~K.
Here's a helpful site for Lansing that Amy was talkin about:
