We are travelling to Germany shortly and my little boy is severely
allergic
to nuts and also dairy intolerant.
I have got a rough translation of the products he allergic to and intend
to
make some small laminated cards for use in restaurants etc. I want to have
a
message at the top of the card in red highlighting that he is severely
allergic and so far have the following:
Mein kind ist zu streng allergisch:
I will then have a list of intolerances below that.
Could anyone who speaks German please confirm that I have the message
correct?

Better:

Mein Sohn ist gegen folgendes äußerst allergisch:
(my son is very allergic against the following)


Many thanks for your help.
