- Showering/getting ready for work or nights out whilst supervising DC
If it was absolutely unavoidable (i.e. Nanny had rebooked night out, and I'd begged for last minute overtime/babysitting and so there was an overlap) then fine. As a routine matter of course, no way. I'd expect nanny to organise her time better, and also expect that being in the job means just that - doing my job, not doing her stuff.
- Helping herself to food/toiletries when doing wraparound not overnights
Depends on what you mean. I can't be that faced about food - as long as eg having a portion of what is there for dinner, rather than setting about the smoked salmon/helping herself to obviously luxury or not-available (for that meal) items. Toiletries - what do you mean? Is this relate to the showering in 1?
- Timekeeping issues - lateness arriving in mornings, not getting DC to school on time
Utterly unacceptable, on both counts.
- Sleeping with DC in parents bed on overnight
Would depend on how this had arisen, and whether any other bed was actually big/comfortable enough for the co sleeping to happen. Is it the co sleeping, or the parents bed bit that bothers you more? I'd be bothered by the co sleeping, unless dc are ill, because that isn't how mine have been brought up, but then again, all mine have ASD, so if it was a needs-must situation (and no one was going to settle otherwise), then crack on. I'd want reasons why it happened, but would listen with an open mind if I otherwise trusted her judgement.
- Taking DC for own medical appointment rather than asking for cover
Tricky. What time was medical appointment. Could it not be made for another day/time? Was it urgent or personal? Again, depends on the situation, and age of dc. E.g. Taking a 2 year old along to an appointment for earache is not the same as taking an 8 year old along to a smear.
- Asking parents to come home early on a babysitting night then going out and calling in sick then next day
First part utterly unacceptable unless nanny is taken I'll (or in my case, dc are unsettle-able (due to ASD), but if she was going out after then that's not the case. Leading to second part, I'd be looking at a warning at the least.
