Should I be upset??

Our son is 11 and in 5th grade. This past Christmas he started showing signs that he doubted the reality of santa. My husband said we should just tell him so he doesn't hear from other kids first. I said fine but I'd like to wait until after easter. Basically for my sake, one more holiday magic, ya know?

Well I come home from work today and my son said that dad told him santa and easter bunny aren't real. I asked my husband what brought that up, thinking maybe my son had questioned it with easter coming up. My husband said no, he had just thought of it and decided to tell him now.

I'm annoyed. I'm the mom, don't I have a say in this?? Am I thinking too much into it?
