Advice please :)

My sister is getting married in a few days and I’m her maid of honor. I wasn’t going to originally bring my 2.5 month old with me because I don’t want her around a lot of people. But my mom was recently in close contact with two people who tested positive for COVID so I don’t want to leave her with my mom anymore. The wedding is outside, so do y’all think it would be okay if I took her to the wedding as long as we stayed away from people and I didn’t let them get too close?

My step dad would hold her during the ceremony and we would leave right after. I am really paranoid about my baby getting sick and I have a lot of anxiety about even thinking about bringing her with me but I don’t have anyone else who can watch her.
