Hi Gwilym. (Not sure if 'Replying' to you is the right way to suggest a lesson.) Anyway, I noticed that 早晚 has a number of meanings. I learnt it as 'sooner or later', but in 'Dads got a cold' it means 'from morning to evening', but looking it up I see that it can also mean 'all the time', 'some time', 'both mornings and evenings', and 'in time'!!! A Qing Wen lesson with example usages of these different senses would be really helpful! Thanks!
