Has anyone given their 20 weeker solids besides cereal and oatmeal?  He does really well with cereal and gets excited. I think he had a minor face rash reaction with the oatmeal. Today I gave him half an ounce of apples to try and he loved it! I know they say wait until 6 months but he seems interested. Has anyone else started at 4.5 months?
