Morning sickness for men

Hey everyone, me and my wife just found out she's having our second child. Super excited about that but what I want to know is, what's up with the morning sickness???? First child when she had morning sickness it seemed like I had it as well and now she's starting to have it again and I feel like shit lol haha. Is it really true that they say sometimes the man goes through some of the mothers symptoms????? Or is it just me and I'm just a hot mess to begin with lol
