Started Baby-let Weaning NEED ADVICE!!

Okay moms, I have a 6 month old son and I saw on this a app something about Baby-led Weaning. I was inspired! This was perfect for my little one. He likes the purees, which I've been feeding him since 4 months old but he didnt stay interested for long and he would only eat about an ounce or two even at 6 months old. So I did some research picked easy stuff to add to todays grosery list, apples, pears, bananas, melon, bread, a couple of egg/dairy free (bc I still plan to keep those out till 12 months) Gruber toddler meals, and I also grabbed a bag of potatoes so I can make him potatoes/formula while we eat my normal potatoes. I wanted to ask what is the safest way to do this? Besides constant supervision. How should I cut the food so he doesn't choke. What's NOT okay to feed him? I gave him crustless thick slices of toast and after I showed him how to eat it, hold it, and he ate 2/3rds of it giving the rest to the dog 😒 Any advice would be GREAT, thank you in advance!! So excited to try this!!👶🏻
