Yes, it is not representative at all. It's a stressful period, kids are always at home as schools are closed, the lockdown requires more organisation than usual in everyday life and there are less options to relieve stress.
We still manage to work with the same productivity in my company but we already had some experience with WFH.
My employer gave us the clear message early on that personal / family care comes first, take the time you need to deal with crisis, etc. And we have indeed had plenty of family issues to deal with and it's been very difficult to concentrate on work.
The problem is going to be when performance is evaluated -- no matter how much leeway has been given now, I will be compared in some respect to my coworkers who have been able to manage this transition better, who haven't had a turbulent home life, etc. etc.
