Help?? Wedding/Baby??

So my partner and I are expecting our first baby at the start of October, which is all fine, except for that his sister is getting married near the end of October and all of his family are expecting us to be there.

Does anyone have any advice on whether it would be okay to take baby to the wedding? Obviously would be carried with myself/hubby for the most part.

( & They’re booking a hotel room on site for us for the night so if baby gets temperamental then I can leave at any time)
