Children's book - Take my paw, little otter

Left alone while her mother went fishing, Miki the young otter soon meets Amak, a young male.   They quickly become inseparable.  But one day when it's just the two of them, a terrible storm arises.   It is by remaining clinging to each other that Amak and Miki manage to overcome it and find their mothers.  When the sea finally calms down, what a joy to know that we are very strong together.

 A favorite album from Jane Chapman.
