I disagree with the things "they are too lazy to do"! It has always been part of a nannies job to do all care for the children. A nanny is generally there the most part of the week, most nannies have child free time, nap times, nursery or school and can chuck a load in the machine, ironing, batch cooking (the amount of nannies I have met in my career of 28 years that bitch about their bosses using the spag Bol she made for the freezer! The parents paid for the food, they paid for the nannies time to cook it, why shouldn't they use it?!)
My charge sleeps for almost three hours a day, the morning nap is generally in the pram/car on the way to his classes and then 2/2.5 hours at lunch time. Twice a week I do two meals for the freezer and twice a week I iron, these take around an hour (I iron my bedding at work too!!) so I still have about hour a day to relax!
It also depends on the family, all the families I have worked for have seen me as part of the family, I still see/speak to most of my previous charges, have them to stay or do babysitting/weekends for them. That's the way I like it! My current family are great, I'm currently living in until separate accommodation is sorted out. They have no problem me hanging round in the evenings or weekends, they invite me to things they are doing, BBQ's/brunch at home. I went to his Cristening and will go to his birthday party on a Saturday afternoon. Sometimes I join them, some times I don't. I like my own space/company!! I think when you care for someone's pride and joy then it's different to an office/shop job. Most nannies care deeply for their charges, I adore all my charges! Even the one that is trying to bankrupt me!!! Most nannies go the extra mile for their employer, starting early/finishing late if the need arises, going in when they are ill (11 days off in 28 years, 3 for slipped disc, 2 for tooth abscess and 6 when I have gone to work then been sent home again as I looked like death!) picking up bread/milk/dry leaning etc. it's such a personal relationship. I like being part of the family, wouldn't want it any other way.
