Which finger(s) should I choose?

Since Colt discovered his hands a few weeks ago, he has now discovered that those hands can open up and he has fingers...and fingers are fun to suck on! Right now, it looks like whatever finger he gets in there first is what he's going to suck on, but the thumb is looking rather promising. I know I should probably push the paci on him b/c you can take that away from them later on but when he sucks his thumb it's just too darn cute! I just can't do it.

He started sucking on his thumb this past Thursday night. Here is a picture of him with his new found thumb and another picture a few days ago sucking his middle fingers. I just love it!
