Too soon after birth?

Okay so, my MIL is getting married a week after my due date. She lives in a different state and my SO is in the wedding party.

My MIL wants us to bring the baby to the wedding (if the baby is on time and everything is fine, of course.)

The wedding is very small. (Only 60 people invited, so far less than 30 coming)

Opinions? Suggestions?

I'm a little worried about brining a newborn anywhere but my SO swears it'll be fine.
