Lots of good advice. I agree with mrs.lotte that a routine is important to allow the nanny to have a reasonable working life. Most nannies (although I'm sure not all) will want to have a routine, so if you are against the idea, you'll have to be sure to source the right nanny. It's a good idea also to seek out a family with similar ideas around child-rearing to your family - e.g. what sort of meals/snacks are OK, whether to watch television, appropriate activities, and so on. A double buggy and an extra highchair or booster chair are useful, plus a travel cot for Child 2's naps if you haven't already got one. A contract between the families (PM me if you want an example) is a good idea - it may be excessive, but on the other hand, it's good to get expectations clarified on all sides. What do you do, for example, when one of the children is sick? Moving the double buggy/pushchair/food in the freezer between houses can be a hassle if done every week. Alternating months is also good. It also means you get one month where your house remains tidy and child-free but you have to drop-off and pick-up, and one month where your house is messy and covered in food, but you don't have to do the drop-offs! You can't always get exactly what you want, but make sure the other family is located somewhere where you can easily 'commute' to and from, you'll be dropping off/picking your child up from there straight from work pretty regularly.
