Are the peds recommending solids? Unless they are, for some specific reason, I wouldn't do it. Babies don't get anything like as many calories from the tiny amount of solids they can eat at this age as they do from milk or formula; it could actually backfire, if she fills up from the bulkiness of the solids, and doesn't have an appetite for the calories in milk/formula.
Didn't Sawyer have an absorption problem of some sort? Are your peds testing Miller for that?
