I'd take them to Cornwall, to the seaside, together, for a week with us, their grandma and grandpa. They don't see each other much and they adore each other - GD is 6, GS is 3. I'd love playing with them building sandcastles, exploring rocks and rockpools, splashing about in the sea, chasing waves, racing on the sand, collecting shells and pebbles. We'd buy ice creams and eat fish and chips on the beach. We'd get sand in our socks and salt in our hair. We'd just have fun, and enjoy precious time together, just being children and being loved, safe and free.
