For those worried about baby led weaning, that is probably a hangover from the days when ours were babies and we were told to start complementary food far too early before the baby was developmentally ready for it and you basically shoved it in and they had to swallow. Waiting until the baby can sit up in a high chair, can pick up small bits of food themselves means that they can control what goes in and what goes down unlike in the puree and spoon days, where there was a real risk of choking. A baby might gag a bit but if they do it comes out again quickly. Actual choking is very rare.
It worried me no end at the time but baby number 1 was not ready for food at the age recommended, and it was a nightmare, thankfully with baby 2 didn't bother even trying until they were that bit older and it went much more smoothly, blw before blw became a thing
