Baby led weaning

I made a post the other day about BLW. My sons Dr said we could start solids anytime at 6 months (she said this at his 4 month appt) and I called a while ago to make my sons 6 month appt (he turns 6 months on december 30th) but they don’t have anything available until February. So i don’t have a chance to ask the dr my questions about BLW. I asked the nurse to call me, and this nurse told me they don’t recommend BLW and to only give him purées until he’s 1. My son isn’t interested in purées. He wants real food. So i really wanted to try avocado or banana or something like that and the nurse told me no even though the dr said he could have anything. I’m so confused.
