I put lack of education. Had I known that it was normal to experience a lull in supply at around 2-3 months, I would've tried harder than 2 weeks to get my supply back up. I did go to clinics and doctor but no body really said that it was normal to experience a temporary drop in your supply. I expressed myself to know end but got too worked up about having to put her on formula, I'm sure it made it worse. I think I would've been far more relaxed and accepting of it, had I known it would eventually come back up (as I understand now, usually it does).
