Painting nursery??

So I have heard many things about pregnant women and being around paint. I would like to help my husband paint the nursery but my mom has a meltdown saying I shouldn’t be around it. I just don’t want him to do all the work and I’m always the one who wants to paint 😂 I need opinions on if I should stay clear of it or help out.. I don’t know 😩 ( no hate please I really don’t know if it’s safe )
