What about BLW? So he’s more in control with it?
Are you doing store bought purées or making them at home? Sometimes the store bought can have off putting taste/smells. I second also giving baby lead weaning a try. Starting solids is more about exploring food than replacing milk so if they aren’t enjoying the experience it’ll make it much harder in the long run. You may just need to wait until they start showing an interest in food as well. 6 months is a recommendation not a rule.
He's probably still not ready, so leave it for a while. 6 months is a guideline, not a target
It sounds like it's just too early to wean him, I'm sorry. I would wait a few more weeks or you might just put him off even more. I sympathise with the feeding though, my little one also needs a bottle every 2 hours and hardly drinks anything xx
