Travelling with children is tough enough, but travelling with children with any other health issue is definitely into the next league. We have a collection of complex issues and haven't travelled abroad once in ten years because it is just too anxiety provoking. The last time was when my twins were two, one drinking elemental formula and one 100% tube fed. This actually made it a million times easier than sourcing free from foods abroad, or having to take ingredients and find somewhere to cook when you get there. Don't get me wrong, travelling with any medically complex child earns you the right to feel smug about what is no small feat when you return home, triumphant yet in need of a proper holiday to recover.... but travelling without knowing if you can actually FEED your child precipitates a nasty churning feeling in your stomach which has thus far put me off trying.
