WTF is up with the expectation on Dads!?

My husband and I both work full time in commensurate careers. We are expecting a baby this spring. I was clear I was willing to have a baby but I was not willing to be a default parent. We have had all the equality talks and I’m pretty sure our daycare doesn’t know I exist. YET STILL when he told his coworkers he couldn’t travel internationally for work more than once a year, because he has a baby to take care of, the response was “that’s a nice thing you do for your wife.”

WTF even is this?

P.S. Not one person has ever told me it was a nice thing I was doing for my husband making half the money.
