Greek baby shower traditions?

My cousin’s beautiful Greek wife is expecting a baby soon, and her shower is Saturday. I’ve bought a present and everything, but I was wondering if there are any Greek traditions for baby showers that I should know about.

A friend at work told me to say something like (phonetically of course): “Na sou zisi”, but she said it’s more for the first visit when the baby’s born.

Just wondering if there’s anything I can do or say as a little extra on Saturday, that wouldn’t look weird coming from a non-Greek.

So, Greek dopers, your thoughts?

Whatever you do, when the music starts don’t throw the baby on the ground.
