The first part of BLW is allowing them to play and experiment with textures. You'll be surprised how quickly he'll figure out how to hold slippery things!
I try to include some things that have a 'handle' so a part that will fit in her fist and something sticking out of the top. Broccoli and cauliflower are great. Baby corn. Other veg cut into sticks. So when cooking our tea I may just cut some things differently for A. Otherwise it's just the same as us. She practices picking up smaller bits.
So tonight we had samosas (I gave her one side of the triangle), chickpea curry (some long bits of onion and mushrooms for A), and naan bread (a length of that too). She's been weaning 2 weeks today.
So, just normal meals but with a little thought about sizes.
Don't expect him to be eating lots. In fact another BLW thing is that you don't worry AT ALL about what they're actually eating! This early stage is all about learning the skills. Picking up food, getting it into their mouth, chewing, moving food around the mouth, swallowing.
