DD was 5m3w and her first real breakfast was scrambled eggs, toast with butter and jam and a sausage patty. She LOVED it and ate a lot of it. Pedi didn't say it was a problem after the fact.
DS was 6m and had meatloaf and sauteed zucchini for dinner then watermelon. Again, my pedi says there's no reason to delay any food beside honey.
