give the baby meat. meat. and meat. liver too. pureed veggies and low-sugar fruits.. i wouldn't worry about faux pancakes and treats -- he's just a baby. keep it basic. i don't know why you're so concerned about having him consume grains? he'll do just fine (and sounds like even better) without them.
are you sure he's allergic to coconut? it's a drupe, not really a fruit -- like olives.
what else did you feed him with the eggs last time? try offering them in isolation. also try for pastured eggs. they generally have a better diet than cafo supermarket eggs.
i'd be a vegetarian if bacon grew on trees.
