We have a couple friend who we were super tight with until they had kids 4 years ago. They never invited us to any of their kids parties (other than the baby shower). I always thought it was weird that we weren't invited but figured that they thought we wouldn't want to come since we don't have kids?

Anyways, I ended up not inviting them to our daughter's christening on the premise that they're not religious. I'm trying to figure out if we should invite them to our daughter's 1st birthday party. I'm leaning towards no.

What would you do?
