Hiya!
I've done BLW with both my babies.
Basically give them absolutely anything from 6 months apart from Honey (until 1yr) and whole nuts (until 3yr). There're no other restrictions.
You don't need to encourange them, just put it in front of them. Their natural reaction is to investigate things with their mouths - you'll have seen her doing this with toys or anything else she gets her hands on. She'll pick the food up, put it in her mouth and most like spit most of it back out. With time, she'll chew/gnaw bits off and learn to swallow.
If something can't be picked up easily (i.e. soup, yogurt, cereal, rice etc) just hand your baby a pre-loaded spoon. They'll know what to do with it! And probably throw the spoon back at you for a refill!
My experience is different for both babies.
MissG didn't ingest a lot until she got teeth at nine months, then got a great appetitie (which wavered slightly according to when new teeth errupted).
MasterG still has no teeth, but there is seriously no filling him. He is such a gannet!
I'd tell anyone who'd listen to try baby led. I've never pureed a thing and have to babies who seriously love their grub
Good luck and let us know how you get on.
