No Tears?

Ok, so I wanted to put this out there while I was on break at work. Yesterday I had Little T's urine checked (no pee for 5 1/2 hrs??!!) and some blood work done. The pee issue was a concern because she wouldn't pee from 9:30 until she woke up from her nap (dry) at 3:00! When she did I ran it back up to the doctors and her urine check out fine.

We also had her blood drawn for some additonal tests. The doctor called poison control when I told him why we wanted a test done on her pee and they advised him to get a few blood tests done too. Anyway, we went over to the hospital and when the nurse saw who she had to draw blood from she called for backup. Little T sat on my lap while one nurse held her arm and the other nurse probbed for a vein. You'd think that a 2 yr old would cry - no, not Little T! When they stuck the needle in she just looked at it then up at the nurse. No tears, no screams, no nothing! Of course the nurses said what a good girl she was - but I just saw her shut down. Now that I think about it she shut down when the other nurse put a bag on her to catch her pee.

What do you guys think? Should we have her evaluated for some sensory issues? Big T said it really bothered him that she didn't even cry but feels I am being silly about the sensory stuff. But jeez...no tears when they stick a needle in her little arm?? That doesn't seem right!
