Garbage in, garbage out

A week or so ago we started Melanie on carrots. Since we do the solids in the afternoon, evidence of what Melanie has eaten does not appear until the next day. So the morning after the first carrot feeding, Robbie sends me an email at work titled, Garbage in, garbage out. He proceeds to tell me that that is an old engineering phrase and that the same applies to carrots... or poop! Lets just say that baby poop certainly changes when solid food is introduced.
