Rude or No?

Ok mommas I need opinions šŸ˜¬ Iā€™m pregnant with my second, and my first girl! We are having a ā€œsprinkleā€ for the baby this week, mainly for diapers and clothes since my first was a boy all I have are boy clothes. Hereā€™s my question - my family is pretty small and when I had my son (my son and my daughter have different fathers) it was just a few people, like less than 10 at his shower. I opened gifts, we ate, everyone left. My boyfriends family is HUGE, and we are expecting 70+ people. Would I be an asshole to not open the gifts in front of them? šŸ˜­ Iā€™m super awkward when it comes to reacting and I donā€™t want anyone to think Iā€™m not grateful for the gifts, but I also hate having eyes on me. I was wanting to take gifts home, open and send person thank you messages but my mom said it would be rude? Opinions?
