I'm thinking about a month as this is what it took last time when DS1 was 7 months old. However, this time I am leaving DS1, 2.8 and DS2, 8 months, so wondering if it will take longer for them to settle as they are both older and more aware. Also, DS1 will start doing a few mornings are nursery. How long should I give him to get used to the new nanny before starting him at nursery? Thanks.
