Would you bring newborn to wedding?

My baby will be three weeks old and I'm invited to a close relatives wedding. She said I could bring the baby if I wanted. The wedding is 30 minutes away. I can't decide if I should leave her with my MIL (who will be fine to watch her and my toddler daughter ) or bring her.

I'm concerned leaving her I'll be anxious and not enjoy the wedding and ultimately leave early. I will also have to pump often.

I'm concerned bringing her that it will be more work/germs. And ultimately won't have fun anyways.

She's just so small to leave her for so long. But maybe I'm over reacting a little and am in my feelings
