Does anybody work 4 10 hour days instead of 5 8 hour days? How do you like it?

We are considering this as an option for next year to give our kiddo who gets overwhelmed at daycare a breather in the middle of the week. The beginning and end of the day are free play and usually when he does the best, so I am not super worried about his day being a little longer...

I am curious about your experiences though! Does anyone love this schedule? Or hate it? Would you do it if you could?
