Why so many Ped HH cases

HI
I am trying to get my foot in the door in HH. My local HH agencies are hiring for peds only. Why so many peds cases and no adults? I found one willing to train me and let me work a shift a week but it is far from home and I can only do shift not per case. I don't want to give up my hosptial job yet I work 3nites a week. Any advise should I take a job in peds / 8hr a week or wait till one of the other agencies closer to home call with adult but that for some reason can be a long time.
Why are there so many peds vs adult HH cases lately
