Absolutely. I would look at my overall budget and see if there are areas I can trim or adjust without real detriment to my family (there typically are). If I can absorb the hit, be it 10% or whatever, I will always go for the happier life.
On the other hand, if you're scraping by now and that extra 10% will raise stress levels and cause additional friction in your relationships, probably not.
Generally speaking, when you get to the end of your days, if you have the luxury of reflecting on your life, happy times will stand out. Having 10% more money probably won't.
