The advice given to us, windmill the arm vigorously, then put heat your hand (I held on to a mug of boiling water). Prick the side of the finger pad, stand up and squeeze the finger downwards so that the drops fall against the lip and slides down into the bottle. Get someone else to hold the bottle with a clothes peg, their finger do not get in the way and it keeps it more stable.
After the kitchen table looked like the chain saw massacre the first time, these hints worked perfectly.
We are doing both swabs and blood.
