Before giving birth to my son last year, I made a pact with myself: if breastfeeding didn't work out, I wouldn't stress or spiral over it - fed is best, and plenty of successful people (like myself and even Michelle Obama!) drank formula. Still, I felt a pang of guilt breaking out those cans - even after weeks of struggling with supply, hiring a lactation consultant, pumping every few hours and trying to wrangle a very fussy, extremely impatient baby. Despite doing plenty of research, the influencer-approved option I chose didn't agree with my newborn.
