I never looked into the BLW materials - kind of wish I had. I believe like PP have said, it involves slicing food into very skinny strips. We did something similar - starting in on grated pieces of certain foods pretty early on. The large grated texture.

DH and I have a lot of experience helping adults with dysphagia (swallowing problems - high choking risks). So we applied that knowledge to feeding a baby. One thing to attend to - what does that particular food do once mooshed in the mouth a bit? Certain foods might seem very soft but if several peices go in the mouth at once, they easily form a "bolus" aka bigger solid ball of food, which is a choking risk! For those foods, we still only give Sprog a few bits at a time, making sure she swallows instead of wadding it all up in her mouth.

If we have another child, we'll certainly check out BLW.
