Today we (Isaac, Joshua, and myself) helped out in nursery at church. I remember when I was required to help out in nursery and not loving it at all. I just wanted to get away from little kids for an hour but instead was with additional little kids. I told myself that I should help out (when my kids were older) to help give the moms a break. Up until this point, I had no desire to do so. But now Isaac is old enough to be an official helper and I thought it would be good to expose both kids to small children.
Both of them did a really good job. Isaac ended up by the kitchen area of the room and stayed there for almost the whole hour. Joshua floated around a little more, but played with the kids well. There were quite a few kids, but only one that had any trouble separating from their parent; it was a rather calm session overall.
You could tell the kids were thinking about it a fair amount, because they had assorted comments and questions over the next few hours.
