Before I was a Mom, I would cringe and pull away from the tiniest of smells.
The smell of anything revolting would revolt me.
But the second my child was brought into this world, everything in the nose department changed.
I'm not entirely sure how this happened, but it did.
My nose can handle anything now.
The nasty, toe-curling smell of baby poop is no match. The disgusting smell (and feel) of 3am throw up all over everything (including my face) doesn't stand a chance.
Hell, I can even stand the smell of fish now, which is a great feat as I could not stomach it prior child.
I'm sure there's no scientific research in this department, but I imagine somewhere in utero the baby plants a chip that allows us to smell crap and live to tell about it.
