shaloow dof !
That is all you get when shooting shutter speed 200, ISO 100, at F-11 or F-8. It is the nature of the beast, nothing can change that unless you focus stack more than one picture. Macro is VERY hard. I am speaking of true macro of 1:1 or greater, not the little flower thing on some cameras.
Yep, the DOF is about as thin as a piece of paper. All you need in focus is the eyes. This particular picture he kept moving his little things that feed his mouth so they could not be in focus because the were constantly moving. DOF on a full frame sensor is harder than a cropped camera such as a 40D. The only good thing is that with a higher mega pixel you can crop it down but I am not used to doing that and it seems like cheating.
I just gave the wife my 40D so it looks like I am going to have to cowboy up and make due with what I have.
