Church Time

We have been taking the babies to church nursery since they were about 9 months old. Brooke has ALWAYS cried when being dropped off, but Caden didn't mind. He loved playing with the other kids and had fun. Our only concerns with dropping them off at nursery was them getting sick, and Brooke having major meltdowns. Well, as of 2-3 months ago, Caden has decided he doesn't like nursery either. They both scream bloody murder when we drop them off. We even arrive at church 30 minutes late (on purpose...to skip all the singing and stay for only the sermon), but they just can't handle 30 minutes without mommy and daddy. Today, Brooke cried, but quickly fell asleep (both church services coincide with nap time). But Caden got so upset that they called me out of church to get him. He was shaking when I got to him. I just don't know what to do....leave them and let them cry...or skip church for awhile?
