HI A.,
First I want you to know I worked as a ER RN for 15yrs so have some experience with this subject. Demand the person who is drawing the blood is comfortable with babies, they are very difficult. Second I highly recommend not being in the room, make them get a second person to hold or have your boyfriend. Why I say this is because you will come in and be the hero when it's done by picking him up and taking him away from the ones who hurt him. I know as a mom of 3 it's hard to leave your child during a stressful situation but it will make the staff more at ease and often the child because he won't pick up on your stress. Good luck!
