I had three holidays abroad as a child, these came about because my father was British and my mother Danish, so on all three occasions we visited my grandmother and aunt in Denmark.
I remember only three things from the first holiday: watching the stokers shovelling coke in the stoke hold of Gullfoss the ship that ailed Leith-Copenhagen- Thorshavn-Rejkavik, a visit to the zoo in Copenhagen, and the red wooden dolls' pram my grandmother gave me -every little Danish girl of my generation probably had one, but they were totally unknown in Scotland! My favourite doll was too big to fit into it, but fortunately, my beloved Teddy wasn't, so the pram was ever afterwards known as Teddy's pram.
I was two at that time, so I think I did well to remember anything at all. Next visit to our Danish family was when I was seven and had been seriously ill. My grandmother paid the air tickets for Mummy and me to travel to Copenhagen, on convalesence - I suspect Mummy needed it more than I did.
I have quite a lot of memories of those ten days. Two years later we all went to Denmark for our summer holiday - a whole fortnight.
I only knew one other child who was taken abroad on holiday, she too had parents of different nationalties.
