I'm a bit stuck on this particular grammar issue:
As a nutritionist, Jane was careful to keep the cookies out of her child's reach. OK.
As a nutritionist, Jane was careful to keep the cookies out of her children's _____.
Reach? Or Reaches?
Intuitively, any native speaker would choose 'reach', as reaches just sounds unnatural, but why would this be correct?
I will be coming over to pick up the patient's file.
I will be coming over to pick up the patients' files.
Are 'out of reach' / 'out of my/their way' / other similar phrases exempt from grammar for just being idiomatic or something?
Expert advice appreciated
