I PROMISE it's not something to worry about. I would suggest stopping and try again in a month or so. If he doesn't like it then, then stop again and try again a while later.
To assure you, first off - back in the olden days, they didn't have baby food. They could only feed babies what they were able to mush up enough for baby to eat. Odds are it was mostly bananas, avocados, and maybe soups and stuff. I really think it's a somewhat recent thing (in the grand scheme of things) that babies have even started solids at 6 months.
I don't really do baby food with my babies. I have tried a little bit with my first three. Some were a tiny bit interested at first, and others acted offended by it...hehe. It was like they were too big to eat it. So, I couldn't get them to take any. I didn't push it. I just gave them table food as they could eat it. This meant they were closer to 10 months before they were eating much at all (my kids teethe later). And, even then, they were still mostly breastfed. With my first two, it wasn't until they were 14 months old that they were taking in significant amounts of food other than breastmilk. They were JUST FINE.
I actually know a LOT of mommas who have said the same thing. I typically find these are moms who are breastfeeding longer and they rely on what feels right to them vs what the doctor says. None of them have had any nutrition issues with their babies at all. And, it was interesting to find out that 14 months was a common number for when babies would start eating more solids, though my third was closer to 11-12 months. They would graze on table food that we gave them prior to that, but it wasn't a main source of nutrition until they were older.
I'm not suggesting you have to wait until 14 months. But don't stress over it. Feed him table food - foods that he can eat (and if there are none, don't give him any yet). Mine were closer to 10 months before I did that. But I breastfed them most of the time otherwise. Your baby will be fine as long as you are feeding him enough milk.
