My sense of smell has always been somewhat lackluster, which has led me to on occasion eat spoiled meat and drink spoiled milk (explains a lot, right?). Fun times. But one of the pregnancy "symptoms" Annie is experiencing is an enhanced sense of smell. I've been able to use this to my advantage :)
"Hey honey, is this milk bad?"
"Babe, can you smell this deli meat? It looks a little... funky."
Alternatively, if I cook something good, to her the whole house will smell like it for a while, so it's in my best interest to cook as much deliciously-smelling stuff as I can. Look out world, here comes Chef Ed!
