Should I see my family or let my son see them

I am in Texas and am 34 weeks pregnant. On May 1st the governor released restrictions for COVID-19, and now most people are going back to work. My mom is working at limited capacity and my grandpa is too. He works at Walmart. My grandpa lives with my mom. My niece and nephew haven’t been around my mom. Their parents (sister and brother in law) are nurses at a nursing home. I have been working from home and so has my husband, so we have still been seeing my family only. I don’t even go shopping.

Now my mom is working she thinks everyone should be like they were before. My niece and nephew are spending the night this weekend, they’re having a birthday party for my niece on Friday, they’re all working etc. My argument is since they’re going back to work they should stick to that for a few weeks, then let the kids come over, then see my sister and her husband and so on. I say to slowly integrate them back in so they don’t infect my mom and dad and grandparents, or they infect the kids and my sister.

I don’t see anyone else or even go to the store, my mom has been going for me. So I don’t feel I count in that sense. Since they’ve decided to do that I’m struggling if I should see my family. I don’t know if I want to see my mom when she is spending the night with my niece and nephew. Or if they’re having parties all together. Just my sister and her kids with my family are 8/9 people.

My son could maybe see them and I don’t, he is 2 and loves his meme and nana more than anything. I’m pregnant and need to worry about the baby and my son. I’m conflicted
