You mean like regular adult oatmeal vs the stuff in the baby box? There really is no difference as far as what's in it, just ground finer...so if you think they could handle the texture there should be no problem...as long as it's still soft and you watch the ingredients list to be sure it's not a bunch of new things at once it should be fine. Same with any other babyfood...as long as it's in a consistency they can handle it should be fine. Hayden never liked cereals much...well he loves oatmeal now...but before I would mix some fruit into his cereal and he loved that, pureed peaches, bananas, applesauce...anything like that
