I appreciate I can terminate the contract and request a refund of the deposit.
However, that is not where our "injury" lies. It is in the fact that finding someone to live in and work with a disabled mother, takes many weeks. We don't have that time. What is more, all of our other childcare plans (and you can appreciate there are quite a few with 4 babies) have been built around our arrangement with her.
We can hire emergency cover for a month or so from an agency. This is wildly expensive at around £1700 per week for live in care. We would have needed several months notice to find another person at £800 per week, take references etc.
Do we have any legal claim to pursue the nanny for the extra costs incurred. It is truly not clear to me I am in position, physically or emotionally (I am in a wheelchair and will shortly have premature newborn twins) to advertise and find a reasonably priced replacement. An agency will provide vetted, professional help - but we would need to recover the difference in costs somehow.
If the nanny/maternity help has so radically changed the terms of the contract after a 5 month agreement was in place, and had done so with only a few days notice, can we reasonably expect her to cover our extra costs of finding an alternative?
