Travelling to Turkey with allergies

[POPCORNx]

I have a 1 year old with allergies to wheat, soya, banana, oats, almonds, coconut and CMPA (plus a few others were questioning awaiting testing)

We are going to Alanya in October and wondering whether we’ll get through the holiday without any reactions?

Can I take any safe foods in our suitcase.. crisps, snacks maybe even emergency baby pouches just in case etc?

He’ll still be on prescription formula as he is allergic to all alternatives we’ve tried.

How much of a nightmare is this going to be!? We are all inclusive. Im hoping we’ll at least be able to get him some veg and potato cooked without any milk or butter without it being too much trouble for them?
