we have been through three food challenges under Dr Lack.
My son was very worried the first time about the IV /canula being put in.
You arrive and meet your nurse who shows you the bed, and than organises the doc to put the canula in.
Normally taken to small room, colourfully decorated, and one distracts , while another puts the canular in the hand.
I am not sure how old your child is? so they will approach it differently with age of child.
once that bit is over, then the fun begins.
You might get to see the woman in charge of play, and all the toys. Getting a playstation set up is a good distraction.
Food wise, its a slow build up, with regular checks of temp, skin , blood pressure, and chest.
The food is increased slowly and ALL of it has to be eaten.
we had a varity of egg challenges with the raw egg put on face first , waiting for 20 mins, then some on his lip, then more checking and waiting.
it gets boring for the adults, the kids spend the time playing.
my son spent some time, playing football with another child in the corridor with the nurse watching closely.
Its a long day.
I hope this helps, any questions?
