I hear so often people say they are doing a mixture of baby led weaning and spoon feeding. I'm not saying one is better than the other, but this is 'traditional weaning', which always advised finger food from 6 months as well as purées. It's not doing a bit of both. BLW means you let your child feed themselves all the time. To say you're doing a bit of both is like saying you're a bit of a vegetarian because you eat some plant based foods alongside meat?
BLW also doesn't mean children don't use a spoon, you can use a spoon straight from the start but you just preload it for them and then let them hold it / put it in (or somewhere near lol) their mouths.
I think maybe people feel under pressure to do BLW but don't want to so they say they're doing a bit of it. There is nothing wrong with doing traditional weaning (purées and finger food) though!
