i think it was a mix of things, moondog.
when i got to the specialist help they said that they find a lot of women on beta-blockers have difficulties with supply. actually, they can't separate it from the high bp, so it could be either. there's no research, that's completely anecdotal from who they get through the door.
also i have PCOS so that might have affected things, who knows? it's not uncommon for PCOS people to have over or under-supply problem. as also the baby came at 38 weeks so, while term, she was on the wee side so she wanted to sleep more than eat.
i asked for help really quickly but the BF counsellors at the hospital said i was doing brilliantly etc (when i just instinctively knew i wasn't). i looked great at it apparently, 'lovely position, v relaxed, a natural', it's just that the baby wasn't getting milk so she kept losing weight. they also told me to pump every few hours, which i did, but the formula was filling her up so our actual bfing time was being interrupted.
so the docs started getting involved and i had to get her weighed every two days.
this was in december, so it was cold and miserable and the baby got a cold so that made her even more sleepy and stuffed up. i do think that expecting to get good care at christmas is a forlorn hope, mind you.
all the while, i should add, she was very alert and bright, so not at all sickly. but i now realise i should have refused to move from my bed, while i was instead driving to the hospital every couple of days because they did rather make me feel like i had a sick baby...
anyway, i was persuaded to give her formula by a doctor who promised that his wife had given formula and it hadn't made a difference... all very well for him to say, and my supply never really recovered. i did mix feed for nearly five months, though, and i really liked it. that was frustrating, i must say, because i just never suffered in the way that so many bfing mums do. no sore nipples (or not that bad anyway) no mastitis, nothing. although i was covered in scratches from the baby clawing at me at night when my supply was zero...
anyway, when i got the specialist help at about five weeks i was put on domperidone (having eaten porridge, drank guinness, fenugreek, other supplements that i cna't even think of now) but we just couldn't turn it around in time. we did a thing where i pumped every two hours for 72 hours, that was supposed to kickstart me but it only brought my yield up to the point where i could give her half-ish of her intake.
in order to keep up the supply i had to keep up the pumping as well, which was a PITA, but i did it. we also latterly went to a cranio-sacral thingybob and the woman said that the baby had something funky about the roof of her mouth, which she fixed, and dd's latch did seem to me to be firmer thereafter. again, not in time though.
so if there's a next time i'll feel a lot more armoured against the paranoia that doctors feed, and i'll be insisting on domperidone from day one (as i'll likely be on beta-blockers again as i am essentially hypertensive) and i'm not moving anywhere.
sorry about the essay, but you did ask. i'm actually shivering just thinking about it. i hope you can see why when people say 'your baby, your choice' etc it gets right up my nose, because i bust a gut and never got to make a choice.
