I have a nanny who looks after my little boy. He is now 2 and she has looked after him since he was 10 months old for £10 per hour. I have now had another baby and plan to ask my nanny to look after him in time too. Will I have to pay her more or is it generally accepted that if they are siblings its all part of the original contract? I'm pretty sure in my nanny's contract is says 'child or any additional children' but its more about her expectations.
