PUTTING FOOD IN THE BOTTLE ???

Has anyone who've had their babies in January 2017.. started giving their babies more than milk in their bottles. Like maybe a teaspoon of rice cereal or a teaspoon of babyfood. Just so the baby can have a different taste of food. I still think my baby is too young but I know she's getting tired of just drinking milk everyday and maybe wants to switch up on some days. Please answer !!
