We've had FT nanny for 8 years to take care of DS1 aged 8 and DS2 aged 4. DH and I both work FT too. Now kids are older and nanny is leaving to have own baby, considering moving to after school nanny. Any advice? We'd need cover if one of kids was ill during term time and during school holidays - is that even possible? Heard that after school nannies typically last 1 year max. Any tips for finding someone longer term? We live in London. Thanks so much for any help.
