DS1 had blood taken at 17 months at RCH they has him sitting on my knee and had me hold him how they told me too, with a toy to distract, then 1 nurse held his arm straight and down, while another took blood from cubital fossa (where blood taken on adults) Was very quick and he cryed for very short time, needed a few tubes. Simpsons band aid on!!

Good luck hope all ok
