Wtf is wrong with people?!

Do you ever have people make disparaging remarks about you or your SO while holding your baby?

I keep running into this and it makes my blood boil. People will talk to LO and tell him how "mean and rotten mommy" is and that I'm doing stuff wrong or how they'll be LO's favorite because "mommy is mean".

I'm probably overreacting, but it really makes me want to snatch up my baby and tell them to go eff themselves.

I think/hope they're just joking and trying to "commiserate" with LO but I don't think it's funny to joke that I'm mean/rotten/whatever.

Do you ever run into this?
