Gosh what a long question/s to answer tonight it will need to be a short one because my charges should be waking up soon for a feed.
Many,many moons ago when I employed a P/T Nanny professional nanny,(children all adults now) Nanny Kate had the choice as live-in or daily. S/Contained cottage was on offer all found & car for on/off duty.
Nanny Kates hours were 8-6pm (then)£150npwk (3 days mid wk)plus £5/6hr (from memory) for over time & for babysitting when available. Responsible for own petrol off duty & any tyre punctures off duty. (would need to seek permission to use car overseas)
Myself having a professional experienced nanny allowed me to see to household, my horses, go for wonderful long rides...knowing @ all times the children were having a wonderful time & always in a safe enviroment. The messy play, art work, mud pies (only a mother would own them)cooking with the children, reading, singing education through play, social activities, T parties, play dates..they always started off clean & Nanny Kate as well...by T-time only the hands were clean & that because they had been washed for tea. The bath my goodness @ the end of the evening..recon we had shares in bathroom detergents. Nanny Kate was with us from 1st child 6mths & NB followed & stayed with us for 8yrs including Nanny Kate getting married (both then lived in cottage, husband followed own occupation) through to Nanny Kate having her own child & then returning after maternity leave to work as nanny with own child...it totally worked for us.
With Nanny Kate who was also on the same way as myself in childcare (perfect of course!! ha ha).
The other 2 days I was able to give full quality time to my children & @ the weekends it was spent with the family as a whole etc.
It work for me & it worked for our family
