Hello! I have a 3 month old who has been exclusively breastfed, but has begun showing signs of interest in solids. He lunges at sandwiches or spoons with his mouth wide open, always seem hungry, and (although much against my wishes) his grandmother gave him some oatmeal yesterday, and he was able to move it to the back of his mouth and swallow quite effectively. I'm torn about this. I would appreciate some other viewpoints. Thank you!
