Blood Test

Watching my baby have a blood test is hard! Why do they have to take 8 vials of drop? In this day and age you would think just a drop should be enough to learn everything they have to know! don't we watch it in TV where they only prick adults and get results? Why can't they do this to babies? To make the matter worst the technician made a mistake and said that one of the vials is not filling up right so he had to threw it out and get another vial of blood! Ah! So unnecessarily cruel!!!
