Girls, Why do your boobs leak when you hear a baby cry?

Anonymous
I was reading this article https://www.romper.com/p/why-do-your-boobs-leak-when-you-hear-a-baby-cry-science-explains-81279 And it says how breastfeeding mothers will start leaking milk if they hear a baby crying and depending on the mom she can start leaking hearing any baby cry, not just her own. Is it true can moms confirm or disprove?
