has anyone ever heard of a boy and girl set of twins sharing one placenta

the smaller girl looks like she's 2 weeks ahead of the bigger boy what ever that means I'm terrified because I have and 8 month old son as well @2mommys2princes2

Usually one is bigger than the other when they share a placenta. Idk if you would want to watch it because it didn't end well for that couple. From what I got out of it the bigger baby is doing more work than the other that's why it's bigger. That's only one story though your situation may be completely different

do u remember what it's called @mommy2be3916

I guess I'm having twins a huge boy and a tiny girl she's only been seen once

I have. I actually saw it on a documentary on Netflix.
