Girls, hi. We've only recently started introducing food (purees) but not everything went well. Broccoli, cauliflower, and green cabbage make her throw up, while carrots and sweet potatoes are missing. What should we do with those products that didn't work for her? Should we wait and try again? Also, meat purees can be tried at 6 months? I think they won't like them either, maybe give them in small pieces by 8 months. I also give her pear and apple in a blender, but after pear it makes her feel sick, she feels good otherwise. Is it worth continuing to give it? Thanks in advance for your answers ?
