Oooh, I'd like to know the answer to this one. We do the 3 day trial for everything, and are still trying what's out there in jars.
I'd love to say we do typical things, but the only thing I try to stick to is Oatmeal for breakfast, and rice for lunch and dinner - with oatmeal for extras if he's still hungry. We've had veggies for breakfast, fruit for dinner, and if he's really tired and falling asleep in his dinner, we might only get cereal in.
I don't think it matters when you feed them what - unless you want it to.
Having parents that have eaten really odd meals at really odd times in really odd places probably doesn't help my son much - he will have food at the table, but there isn't much of a schedule beyond feeding him when he's hungry.
I figure if we get the cereal in that the pediatrician requests, then we're fine. :)
