So surely it wasn't that [oestrogens]that caused the baby to vomit?
Perhaps PMT in mom led to anxiety and nausea in baby???

Perhaps. But what effect might prostaglandins (or other hormones we haven't
even considered) have? I don't know. I do know lots of women whose bowels
are looser pre-menstrually, and one super-scientific researcher who tested
his wife's milk for prostaglandin levels and found them elevated
premenstrually. Why did he do it? baby was noticeably grumpier and poo-ier
all round on the day day before the period began. Like everything else,
we're all on a wide spectrum of normal re hormone levels. Why should
gastric hormones make some mothers nauseous or even vomit when let-down
hits? who knows, but they do. Solution, by the way, is not to breastfeed on
an empty stomach! And then there are headaches triggered by milk
ejection... the range of things we don't know never ceases to amaze me. We
could write the exam no healthworker could pass!

Calcium, Dianne: contact Ann Prentice at the Dunn Nutritional Lab, Downhams
Lane, Milton Rd., Cambridge, UK CB41XJ. She knows more about calcium
metabolism in lactation than anyone I ever heard!
