Posted in teen parenting but i dont know what to do, when can i start giving gracelynn cereal? I know not all the time, but when should i start.. please i am just asking when is right, not looking to be riducule becasue i was giving it to her since she was born(doctors told me to for reflux,in her bottle but quit it at like 1.5 months) *Update* Well guys gracelynn is 4 months old. About 3 days ago I gave Gracelynn cereal and the end result was awesome!! She at first was hesitant but then she chowed down on it. So i gave it to her again last night and well the results were even better. She even tried to feed herself. She took the spoon and wiped the cereal all over her face.
