We are very lucky. DH can work from home and is in a secure public sector job. I am a carer for our 12-year-old who has autism and special needs so will be able to look after him at home if / when schools shut. DD is in year 10 and has some GCSEs coming up ........not sure what is going to happen there! It's not the end of the world if they have to be done later in the year.
Financially we are ok but so many of our friends and extended family are in vulnerable positions - self-employed/working in hospitality etc.
My biggest worry is for my parents and in-laws who are all in their late 70s and 80s..........3 out of 4 have serious health conditions which make them very vulnerable.
