I am also wondering whether the baby who is on meds for reflux (cries a lot, but gaining well) isn't on the receiving end of "oversupply" and/or "overactive let down" syndrome??? It could explain the spitting, the crying, and the gain... Lisa Jones, LLLL, in Wellington FL - who has seen several moms with oversupply recently who are *very* relieved that it is a breastfeeding "management" issue and nothing worse.
