If you had heartburn with one pregnancy, did you have it in all of them? Or just particular pregnancies?

I know it's been asked before, but I don't know if I saw it for multiple pregnancies.....did the heartburn correlate to your baby having lots of hair?

For me, I had horrific heartburn with DS1. He was born with a mohawk, though it wasn't super thick hair.

This pregnancy, with DS2, I have heartburn again, but definitely not as bad as the first time.
