Rate of hospitalisation by age band gives a pretty good proxy as to severity of disease by age band.

Chart below gives data from NSW.  Unfortunately the columns on the right don't give much of a guide as to how much worse delta is, as rather than "then and now" it's "total and now".  I think someone with an agenda may have influenced how that data is presented.

Anyway, in an immunologically naive population with a large outbreak but still with a high probability that most cases are being picked up by PCR, only 2-4% of age bands under 17 are being hospitalised.

I did read a news article about a higher ratio (~25%) of the young children who are hospitalised end up being admitted to ICU than other age groups (IIRC this was public data from US CDC) but that's not showing what it may seem to be at first glance.  A higher % of the low number of children admitted to hospital have co-morbidities, so as well as being far more likely to get sick enough to need hospital care, when those with co-morbidities do get sick, they're much more likely to get very sick - when most kids without comorbidities don't get very sick - if at all.  (Hope that makes sense).

The stated 11% of all cases being admitted for hospital care in NSW is very frightening.
