It depends on the partner’s salary & your outgoings. When our youngest was small, H was taking home £1400 a month & our mortgage was £1000... not rocket science to see I had to go back to work

Now he’s earning more & our mortgage is less I think we could do it. We don’t have expensive cars (we own our cars outright; they’re not fancy), holidays, lifestyle. But with both kids school age I don’t think I could live with myself sat around all day! I’ve earned my own money since I was 14/15 & was the higher earner before we had kids.
