Dc1 is almost 5. This last week, I have noticed him making a noise. Mostly when having a bedtime story, or when watching tv, that sort of thing. It's a " hmm" sort of noise.
He has hayfever a bit and a tickly cough, and throat clearing. He said this noise is because of the cough. It seems more like habit (and it's really bloody annoying, but I'm generally ignoring it. )
Does anyone have any experience of this sort of thing?
