Just in the interest of balance, it is my husband who has on more than one occasion swooped in to save DD by leaving his office and going down to her school. My mobile phone is usually switched off.
As to whether DC need saving, yes, you can drop them on their sorry arse to face the ramifications/consequences of being forgetful/disorganised or you can mollycoddle/save the day.
On the occasions I have opted to do the latter it is probably because my kid would have been less disorganised had I myself been less flaky. It is all very well to talk of kids' self sufficiency and accountability but where parents are being crap/borderline negligent (like when I forgot to wash the P.E. kit and no, she wasn't old enough to have done it herself) a little kindness/flexibility goes a long way.
That said, my DH and I would never rely on an office
We would either:
Directly meet her during designated break time for handover
Embarrass her in front of friends/staff by doing a visible handover so she gets better at not forgetting random crap
(Not UK)
As a former teacher though, it would not have bothered me. But as I was being expected to chase/sanction every missing/late homework
and ridiculously in one school, never have any missing/crosses/black marks ever...yeah, right. So, in that regard, parents making an effort would have been doing me a favour. Similarly, if they wanted to bring in £ that at one time, I was being expected to collect in, or kit or equipment or ingredients....hell, we all have off days. If it was every day then unreasonable but otherwise
