Oh well, he was fine once they were done and I picked him up.
I admit I'm a mean mom because I decided to continue the torture and had the lab do a blood test to check his iron levels. Hey, one really bad doctor visit versus two yucky ones; get it all over with in one shot! Poor kid had to be poked again. He of course, liked this as much as he liked the previous needle pricks.
I'm happy to report that his iron is at a normal level so he no longer needs his iron supplement. And, the little guy is not so little anymore. New weight total: 11 pounds! :)
