If she doesn't want any food after several tries, she is telling you, I'm not hungry anymore. Serve Baby only one new food a week. This month the new food will be different cereals. Stop feeding the food to your baby if you see any of these signs. If there are allergies in your family, your doctor may suggest that you wait awhile to starting feeding wheat, eggs, and dairy products.
Babies have a keen sense of taste.
Some babies show that they like some foods and don't like other foods. If she doesn't like a food, don't take it personally. Serve the food in a few weeks. Baby may like it then. Meal time is a time for loving and learning as well as eating.
