Sorry but these parents need to suck it up. Some, but not all parents, act like their kids are a big inconvenience being at home. They need to chill and enjoy their kids. If their kids are in elementary school then put school in perspective. It’s elementary school. In the big scheme of life, grades in elementary school are not that important. Do the bare minimum, stop stressing and stressing out your kids.
I was a SAHM. Loved my kids being home. Most of the time they entertained each other. Life doesn’t have to be scheduled.
