cadburys festive friends biscuits

[eragon]

anyone had any problems with them?
my son has had a mild allergic reaction to them but nothing on the ingriedent list is any of his known allergens.

no allergy box with any potiential trace of allergens on packet.

I would be careful with Cadburys stuff, my DD had a reaction to buttons several times despite them not containing nuts.
Many things are made on production lines that use nuts even if they are not in the ingredients, not just at Cadburys but lots of places.
Do you have Tesco near you? They label all their own label stuff with information about if the production line/factory uses nuts.

DD ok with these, despite nut allergy. Hope your DS is ok
