First time:
despite feeding on demand, I kept detailed records of how long feeds were, when they started, on which boob, and spent ages trying to analyse these findings for some sort of pattern Second time: again, feeding on demand, but the idea of writing all this down makes me laugh
When my baby girl fussed and fussed for the first week, I thought it was colic until we took her to Emergency and discovered that I was underfeeding her because I wasn't making enough milk,
despite feeding her on demand and pumping and taking domperidone.
