It works, IME, with very supportive grandparents, working locally and having your children at your school (primary)!
DH is self employed, so sick children are covered by grandparents unless it’s D&V, to avoid us losing money as it’s very tight financially - even with me on the upper pay scale. He also leaves at different times each day and only has two seats in his vehicle thanks to equipment, so all drop offs etc are on me.
Typical day involves dropping DD2.5 at grandparents in our village, then DD5 and I heading to school in the next village for 7.30am. She goes into breakfast club while I set up/do admin. She then has a packed tea in my classroom and colours etc until I’ve done marking/admin, then we collect DD2.5 from grandparents and get home for a little play, reading homework, bath and bed. DH does all cooking etc. I then work on the sofa with DH until about 10pm. Weekends are spent doing house/garden jobs (DH is brilliant and I only do laundry and general cleaning; he deals with everything else) while dashing around to swimming lessons, parties, play dates etc.
My in laws are literal heroes, and mean that we don’t/didn’t have to put DDs in long hours of childcare.
Parents evenings etc require a bit more planning because DH needs to ensure he is working locally on those days and has to have my car to collect the children. When we got the Ofsted call he had to apologise to his clients about leaving early to take over from me for a few days!
I wouldn’t change my job (yet) because I love it, and the holidays with the children are just glorious when the weather isn’t shitty.
However, I am nearly 15 years into my teaching career. I can mostly plan with my eyes closed, and am suppported by a wonderful headteacher and have earned enough respect from families that parents don’t give me too much grief. This is not the case everywhere. Please read information from other posters and go in with your eyes fully open.
