well, we have always lived more simply than all our friends,so we just got used to feeling like we had 'less' sometimes. We have always chosen the one income lifestyle for ourselves,and chose accordingly. Homes,cars, purchases,etc.
When the kids got older, they had a harder time coming to terms with our simpler choices frequently,as it meant that on an ongoing basis,they had 'less' than their friends.
So you just get used to it. However, when times get tougher,and friends tighten their belts,our life doesn't change too much,and now some people feel like we have 'so much.'

I guess I think it all depends on perspective,and how you choose to view things.
If you can, plan as much free/cheap fun stuff you can for your family. Scour internet and brochures,enter sweepstakes,sign up for every email list...deals come along,and when you can afford something,do it!
Get a library pass,and go to a local museum! invite friends over and share a potluck meal and some games- free!
experiences are more valuable than things,and the best experiences usually don't take much $$$,just effort and thought!
For that matter, take the fam to the library and check out piles of good books and movies- make dinner together, go sledding with friends, go to a beach an swim, have a picnic, go hiking,etc etc.
view your financial struggles as your personal path to making your familys life better,and plan for what you can do....helping yourself and making goals along the way. Life is a journey,and if you can't afford something this year,then dream for next year,or after that!
