One hundred days of 'hell'?!

TNY • Scientist. Wife. Mom to 🐶 (2013), 👶🏻 (05/16), 👶🏻 (06/18), 👼 (03/20), 👶🏻 (12/20). Starting my advocacy for the disability community 💙💛.
My LO turned 3 months yesterday and I was telling a friend about my "journey".... She called it the common 'one hundred days of hell'.... I had never heard of that saying. Have you?
My first one hundred days have included mastitis, food poisoning, thrush for the past two months, acid reflux, gas, being overtired, and fussiness. Honestly, I would not have it any other way ❤️
What does your first one hundred days look like??
