I am going against the grain here.
No they don't.
beofre you bash me. I am an (ex) teacher. I have 3 kids. My kids primary school was 89-90% teachers who did not have their own kids, and of those that did, several had babies/toddlers.
Some of those teachers were amazing, but there was definitely a divide in understanding of life at home between those who had kids and those who didn't.
Just one small example, teachers asking for something with 7 days notice or less (dress up days, bring a photo of your grandfather into school, whatever). As parents we asked and asked for more notice and for dates of important things to be given out at the beginning of term.
we went through 2 heads, and no difference. then new head, with school age kids arrived, and without asking, we suddenly got information in advance.
I have lost count of the number of times I have mentioned to teacher that xx homework caused lots of stress, to be met by a blank look. That ds did everythign exactly as asked in school, at home, the words blood and stone spring to mind.
I have a huge respect for teachers, and think that they have been wonderful through all this, and gone massively above and beyond. My kids are now teens and the issues are different, the motivation is now them and their exams.
But I do think there is a large dollop of naivety from teachers without kids. I have been that teacher. I had no idea!
