Little bear was awake for a lot of the night coughing. I went up a few times, but he was not in a humour to be comforted. Then I remembered a quack remedy I had heard in the playground. I rubbed the soles of his feet with vapour rub - my version is a generic rip off of Vicks.
And it really helped!
Little bear as ever did not sleep in but was not as grumpy as he could have been. I shall try it again tonight before he goes to sleep.
