Hello ? How did you start the first feeding? And from what did you start? How did you give it, how much and what? Today I bought two jars of puree, with broccoli and meaty, before the mixture gave her a teaspoon, so he grimaced ? threw up, broccoli something didn't go down, well, though the first reaction I think he should get used to then, or do your kids immediately eat new things? We will be 6 months old soon, 27 kg to the doctor, but I don't want to wait ?
