"Baby Lead Weaning" appears to just be unnecessarily formal language for what Mums have been doing for ages with their children - giving them bits of the 'proper' food they are eating.
That comes naturally to us, in our family. Not all the time, there will be spoonfeeding too. But when I'm doing a meal, DD will get a bit of whatever we are having that she can hold.
On Sunday she had a broccoli floret in her hand for a while. Then a roasted parsnip baton. Not made especially for her, part of our Sunday dinner. She's been joining us in the highchair for our meals for a while now.
She didn't eat, DD is only 5 months so this is just about discovery not eating. I just put the thing in hand for her to feel, squash, play with, put in her mouth (as everything goes in her mouth) and spit out (tongue thrust reflex).
If you are looking to do BLW you can't beat bread based products for early easy food - something spread on bread or toast, bagels, muffins, that kind of thing.
