When my girl was 6 months i used to make this with fish fingers (yes more faffy then just serving but another way to try if you wanted to) xx https://vm.tiktok.com/ZGdJdB2SY/
Always given just breaded fish fingers from 6 months. I don’t really care what my kids eat as long as they eat it and are happy😂
Perhaps you could get some with actual batter instead of breadcrumbs? I gave my LG (also 6 mo) one with the batter on and she got on okay with that (I did end up taking the batter off for her but it didn't crumble!)
