7 Week Old Baby at a Wedding? Read below

We were invited to a wedding in June and our baby will be about 7 weeks old, I'm wondering if we should plan on bringing the baby or find a sitter?

The wedding is for friends that we are close enough to that I would like to attend, but we aren't so close that we are in the wedding party and I wouldn't feel obligated to stay the entire night. The ceremony starts at 3 and the reception is at 530.

I have no idea what is socially preferred, or what a 7 week old will be like at a wedding.

What do you guys think? Do we bring the baby or leave it with a trusted sitter?
