BLW is great. My youngest has issues with consistency, or had mostly, not so much now. But when we started him on solids at, eh, 6.5 months or so? it took some time before he actually *ate* any. He tasted, chewed, played with it, and got some into him. But I think he was like 8 months before he really started actually eating what I would call a meal of solids. He wouldn't eat oatmeal until he was about a year old.
We started with veggies, fish, and fruit/berries.
He eats most anything, and loves fish.
