Girls, hi ? Can you please tell me what to do with feeding, because it seems like we need to give water when introducing solid food, but the problem is that the child doesn't like it ??‍♀️ He even has an aversion to vomiting reflex, trying through a bottle and spoon, I tried making homemade juice without sugar, too, it didn't work either. The pediatrician advised giving children tea, I read that many teas contain sugar, so what should we do? What do you feed kids in our age group? Give me some advice☘️
