BLW question

I would really like to start with my 6 month old but I am SO nervous! She shoves everything in her mouth, so couldn’t she bite off a chunk of banana or something and still choke on it? I’ve researched blw a lot and know how to cut the foods, how soft they need to be but it still makes me nervous. Also I know it’s not something I need to do, but I do think it would help her enjoy veggies and other foods besides fruit.
