it was me who linked to the story on the blw site, sorry for worrying you. i thought it was a good description of choking, as opposed to gagging.
didn't you notice that the kids were all older than weaning age, though? and that BLW wasn't mentioned, so that guarantees that none of them were BLWed. because believe me, if the DM could have got a 'new weaning trend kills babies' story out of that, they would have done so with great gusto.
there was a thread a couple of days ago where a child had choked, properly seriously choked, on a bit of scrambled egg (the poor mum had been out of the room for a short, short time but in those minutes...) again, that baby was 11 months old, well past 'weaning'. again, no mention of BLW.
the fact is, kids can choke, and the smart thing to do is take measures to prevent it and know what to do if it happens.
keep an eye on them when eating, cut little round things up (or smush them, basically stop them from being little round things...) and educate yourself on what you would do if the worst happens.
i've said it before, but the only time i've had to do a proper 'turn them upside down and SLAP' thing was on a toddler in the park. no-one else knew what to do, or if they did, they didn't do it. i was just glad i was there as god knows what would have happened if i hadn't been.
