Is it weird Baby hasn’t had a lot of food yet?

My Pediatrician said to do one food every 3-5 days. This is supposed to be experimental and introducing phase, right? We started at 6m and she just turned 7m so it’s only been a few weeks. I see everyone else posting about SOOO much food. I don’t get it, am I going too slow? FTM, I hope I’m not doing my LO a disservice but at the same time want to follow doctor.
