Hello. I am curious, about costs for watching two kids. I have a toddler who is 21 months and newborn baby 3 weeks. I understand separately, we would pay our nannies/sitters to watch 10 pounds an hour. How much if we want them to watch both? My husband said it should be the same - but in my opinion it is more work! So wouldnt we pay more? What are the costs to watch two kids?
