Nappies and infant milk are the two lines we never allow to run out, because running out of them is not an inconvenience, it is a crisis in somebody's house at two in the morning.
We keep a buffer of both, in the common sizes, even when it ties up money. Soap, shampoo, toothpaste, sanitary goods and simple medicines sit beside them.
If you have a baby on a particular milk, tell us which. We will keep a tin back for you on each boat rather than leaving you to find out on a Thursday that somebody bought the last one.
