DD1 was with her GM five days a week whilst I worked and GM was of the boil it for two hours and then pureé it to death because otherwise a baby will choke and die opinion. Didn't find out until years later when I was trying to get her to eat more than a tiny scrap of perfectly smooth things that she'd choked three times on pureed banana because it turned into a perfect, sticky glue compared to being able to cough a piece of it out or chew it small enough to swallow in smaller quantities and had therefore not been given any solid food whilst there for four years. As an adult, DD1 still only nibbles at little scraps of anything that isn't soft as she's still uncomfortable with chewing. Her speech was absolutely atrocious as well, because she wasn't getting the practice of using her lips, tongue and teeth to eat three times a day.
DD2, however, was with me and then a childminder. She was grabbing at any undefended plate from 4 months, practising fine motor control at picking bits up, smashing broccoli, pinging peas across the room and fighting for both spoons and anything she could pick up and developed dexterity from putting food in with her left hand, chewing and then a spoon of softer but textured food for her, one for the dog (splat) and one for the cat at every opportunity. And my goodness, did that child learn to talk quickly. I'm sure it was largely with the intent of arguing with her sister, but she went from clear as a bell 'Mama' at nine months to clear as a bell 'No, <sister's name> - you smell' in a blink of an eye.
You know what the signs are of choking, you know how to deal with it if it happens - you've had the training, which means that you, like most parents, will not freeze and cry, you'll instantly pick your LO up and go slap-slap-slap until whatever it is clears. That's why the training is so useful - it enables you to override the 'What do I do? What do I do?/I can't possibly hit my baby, I just can't' in favour of the far more useful 'Choking-whack' instinct.
There's no nice way to say this - even if you had to break every rib (which you won't, it's more like striking a drum or a box with a flat hand to make a resounding noise than it is something trying to hurt), it would be better than watching your baby die in front of you. So it might not be 'nice' to need to do it, but once instinct and training takes over, it's not traumatic for either of you.
