I have two weeks paid sick pay in my contract. I also have references that state that I never took many sick days and some say that I came in when I really should have been in bed. (9 days in 28 years!)
I also don't think she needs to be in before she starts work, if there is anything you need her to know, write her a note or text her during her working day, there is no need for a hand over in the morning, but 10 minutes at the end of the day is nice. Don't do what one of my ex-bosses did and spend 10 minutes telling me about her day and then asking about our day when I should be leaving to go home.
It depends what she will be spending kitty money on. If she is working 5 days then she'll probably want to do classes, I don't know where you are but where we are, classes range from £2 to £8 per child per class although there is usually a lower rate for a second child. We do classes 3 mornings a week and swim one day, which comes to £23.50 a week for one child! I also buy bread, milk, etc, dry cleaning if needed out of kitty. Last month I spent £180 but included new shoes, two dry cleaning bills and a birthday present for a friends party. It soon adds up.
I quite like to be thrown in at the deep end with older children, it's quite difficult to bond with a child when they only want mummy! However, I have only had babies for the last 21 years so have had one to 6 weeks hand over, babies don't care as long as they are fed and cuddled. I also disagree with not letting nanny go early, start late if you are going to be around, your child will only want you after not seeing you all day. If you come home early to do something, then try to sneak in and stay out of the way until you are finished. Its not fair to make your nanny the bad guy, having to tell your toddler, no you can't go and see mummy, and drag them screaming away from the room you are in.
Yes you should at least offer your nanny lunch, I eat whatever my charge is eating, maybe a slice or two of toast for breakfast, tea/coffee and biscuits/fruit for the odd snack. Ask her what she wants for lunch, show her where she can make a shopping list or give her the password for on-line shop so she can add things. (I do the on-lube food shop for my employers and leave them a food plan for the week!)
Always leave the house as you expect to find it when you get home, don't leave a full clean dishwasher and all the washing up from the previous evening congealing in the sink! I can let a couple of mugs and a bowl go, anything more than that pisses me off. Say thank you, show respect if you want respect returned, appreciate her if she does a good job and occasionally tell her how you couldn't cope without her!! The best one from my current boss is - having a nanny makes me realise that we needed a nanny way before we had children!
I think this is long enough now!
