I took Joshua to get his blood drawn today. Poor thing was really trying to work up his courage. He would pinch himself in the crook of his arm to try to mentally prepare himself.
They called his name and we went back to the room. Joshua was still trying so hard to mentally prepare as the latex tourniquet was tied on one arm then the other to check his veins. When the time came for the actual puncture though, the phlebotomist quickly realized she would need help holding Joshua's arm still, so she called in a colleague -- another nice young lady.
They held Joshua's left arm (the one deemed best candidate) and I held his other hand and talked to him.
I was so very much hoping it would go quickly, as it does with me. I have veins very conducive to being stuck.
Joshua, sadly, has his daddy's veins. They seem to avoid puncture. They roll. Ugh!! Poor thing!
It took quite a bit of maneuvering under his skin before the needle was able to puncture a vein.
Oh my goodness.
But he was so good. He was crying and not liking it a bit, but stayed brave. I felt SO BAD for him, but maintained my calm. (Thank you, Lord.)
As a reward, we took him to get sushi (his absolute favorite food). We ordered a lemonade for him while waiting for our food. He took a couple of sips and next thing I know he's telling me he does not feel good.
We were the farthest from the bathroom and Joshua is a very slow walker, but, glory to God, we made it in time for him to throw up in the toilet.
He is always so amazing when he's not feeling well. While still standing in front of the toilet he said, (TMI WARNING) "On the bright side, at least it tastes good" (like lemonade). 
We went back to the table and I was sitting across from him. I have never seen him look so pale. He had no color in his face except for a little blue on his lips. He also said he felt very cold, so I took him outside to warm up. We sat on a bench for a bit and his color returned.
So we went back in to join daddy and have the sushi which had arrived, and we lived happily ever after.
Phew! Glory to God! Thank you all so much for your prayers!!
