BLW wuestion

I don’t do BLW. It’s not for me because I’m paranoid about baby choking. However, I’m fairly lenient and try to let baby try different things we eat and I want to let him have finger foods. He does well with food in general. So... I made him some BLW muffins as something to gnaw at while I make his meals. He loved it but I ended up taking it away. I felt like he was getting too much in his mouth at once. How do y’all prevent baby from gnawing off too big of a bite or not getting to many small pieces in his mouth at once?
