I WFH when DCs were young. The only benefit in childcare terms was lack of commute. I still had to pay for childcare as I couldn't WFH with children in the house. (Boss wouldn't have bothered but I couldn't have done the job and looked after DCs)
I work mostly from home and I'm struggling - no colleagues, a demanding toddler in the day, sit down to start my paid work at 8-9pm so very little downtime and going out for an evening wrecks my schedule!
