It's not a job where you can drop your kid at school and collect them at the end of their day. You'd have to have a childminder or they would go into breakfast and after school clubs.
Primary generally requires lots of daily marking, so you'd be there until at least 4pm (if you mark through your lunch break). Plus you'd have books to take home regularly and planning after school/in the evenings based on how that day'steaching and learning went. So even if you do leave ten minutes after the children do, you'd have a load of marking and planning to do that evening at home.
Also be prepared for your head to be inflexible when it comes to going to your own child's performances or assemblies, so you'll miss those.
I love teaching and I think I'm good at it. I love the buzz when children really click with what you're teaching and you can literally see the light bulbs going on in their brains!
But I'm looking to leave at the end of the academic year. Not because of the teaching, but because of the constant scrutiny, the micro-managing, the lack of flexibility, more SEN needs but less help, the lack of support from parents etc. etc. and the way education is moving from a creative, inspiring profession to a learn-by-powerpoint, mind-numbing slog.
So, you know, best to go into a local school and shadow a teacher for a week to make your own mind up!!
