Unfortunately i believe they do, even those sold at health stores. There's a page called eating in color on Instagram, great page that's full of knowledge. For my kids, I would just buy the frozen veggies and mix with pasta sauce and small pasta.

If you have time you should make ur own! I did baby led weaning, it teaches the first 100 foods you could give before they turn one. I loved it you should check it out! I mention this bc it talks about how your baby can eat a lot more than u think (like not just purées)
