ds is due to have a food challenge soon for tree nuts
today received letter about participating in study that I would usually immediately agree to as feel the more research done the better for us and others living with allergies
however this one means ds (8yr) having blood taken before and after food challenge , and then once or twice more at later dates
ds has had blood taken , he was very brave and coped well with lots of cuddles
now I could quite easily say yes to this and ds would get all the blood taken anyway as he's a child and would think it was just what is needed. He wouldn't enjoy it but ultimately wouldn't come to any harm
But should I tell him it's voluntary and let him say no if that what he decides despite me explaining the benefits of research etc.
Or just say yes and leave him none the wiser ?
Preparing for a flaming here.
