What do I say in response to hearing about the first communion of a child?

Not being Catholic, I realize that first communion is significant, but I don't get why it's something that one should be congratulated for. I get that for Jews a bar mitzvah reprints a boy becoming a man and can see why a congratulations would be appropriate, but I don't get the significance for first communion.

You say congratulations for milestones. Getting first communion is a big milestone for Catholics.

How about "that must have been a really big day for you!"
