Really do sympathise op. Thankfully my youngest will be in school, by the skin of our teeth.
It's a fucking impossible situation.
Very easy for people to say that husbands should step up. My dh has to work away a lot of the time or is travelling up and down the country. He has to go where the work is. He cannot just wfh or ask to finish at 3 or nip home.
He already used his pittance of a holiday entitlement stepping up during the last closure, then when one dc had to isolate, then took an unpaid period when one of us caught Covid.
His is the main income, my salary doesn't even cover the mortgage.
I'm not classed as a key worker, but I'm still expected to go into the office, can't be furloughed (public sector). No flexibility in working hours, expected to be available during office hours.
First lockdown I did wfh, while my poor reception age dc was left to watch tv and 'play' alone for hours on end.
Choice is work or neglect your child.
