when i was a teenager my mom was in charge of the nursery's on sunday mornings which meant i was able to go into the nursery and be involved with kids that were really young (3 or 4). i remember what great times i had. here is a blog post by mark driscoll who shares his experience with kids.
As a new Christian and college freshman, my first ministry was taking care of a bunch of young kids during a daytime women’s Bible study. It was the best. The kids were super fun, and on any given week I had anywhere from maybe 10 to 20 kids under the age of five for a few hours without any help. Those hours included crackers, juice, Bible stories, wrestling for the boys, and tea parties for the girls. The moms were surprised that a 19-year-old single guy would volunteer for the nursery, but I’m glad I did. And I’d encourage the same for other single men. In fact, I have nine reasons why single men should work in the church nursery.
