I'm completely paranoid about choking because DD1 choked on a piece of fruit when she was a baby and I had to Heimlich it out of her. Scariest ten seconds of my life. So we do not do BLW here. At 11 months (and no teeth) DD2 is still on purees/soft foods and foods cut into pieces smaller than her airway. Last couple of months she's become really determined to bite off her own pieces of food so I have just been steaming everything to a very soft texture before I give it to her.
I agree with what others have said that there's nothing particularly nutritious about grain-based cereals, we started with soft fruits and veggies steamed and mashed with butter (banana, avocado, roasted sweet potato, steamed carrot, steamed sugar snap peas, boiled white potato with steamed broccoli) and quickly added in egg yolks and rice/lentil cereal.
