Some churches have people to work the nursery, others feel it is the responsibility of those using the services, as in you put your child in the nursery so you need to work in there every so often. I have been a member of both types of churches. It sounds like your church is one that uses the people who leave their child there as the workers. If that is the case, you must work in there, or you must not leave your kids there. I used to like working in the church nursery before I had kids. Not anymore. So when I went to the church where they had it set up for people to work who left their kids, well after a few times I took my kids out and just took them to church with me. It was better than having to work in the nursery. Yes, I didn't get to hear everything in the service, but it gave me opportunity to explain things to my toddlers. And people were very kind.
