BLW question (signs of readiness)

My baby girl will be 6 months on sunday and im really excited to start her on baby led weaning! I follow the group on fb, but their posting is closed for today, so im going to ask this here! So..

This girl right here is sitting up for minutes at a time, she shows LOTS of interest in food, etc etc. The only sign of readiness im hesitant on is the grabbing. She tries very hard to grab things and when she does get it finally she brings it immediately to her mouth. I just dont know if i should wait to start her on blw until she can grab things better?

In all honesty, i tried to give her some cauliflower and a baby teether wafer tonight (i know i know, shes not quite 6 months yet, but its only 3 days away!) And she got really frustrated because she couldnt grab the cauliflower. She did okay with the wafer, and ate most of it, but i think it's just cause it stuck to her fingers so much. I realized maybe shes not ready yet, but she literally shows EVERY other sign, and she does grab, it just takes a little bit. So do you think i should wait until she gets better at it? Or should i just let her keep practicing with the food (even though she gets super mad)?
