Moving up grades in job

So I am currently at the top of my hse scale, it’s currently sat at 55k which i am very happy to be earning. New baby just arrived a few months ago and loving it, our families mortgage is low enough in comparison to some of the bigger ones out there.

I have decent flexibility now with hours and Moving up a grade which maxes out at 62ish, I would lose those hours and also possibly bringing work home to prep, which I dont need to do now.

Is it worth the extra few hundred after tax?

Now I’m not afraid of progression or learning but think since having a family time is more important. Anyone been in similar situation?
