Below is a link to a really good article I read about a mom who stays at home, despite being a lower-income family. I found it encouraging because her tips are very real to what we (mostly) already do. And it was also encouraging to know that our family is not alone and that there are families out there in the same predicament of trying to get by in today's world. And she thanked God that they can with what they have. Awesome.
