I love being a stay at home mom! My boys are now and We had really lean years for a long time. Day old donuts for a quarter were a treat and we cut them up as crumpets. :) Kids don't need lots of things. I'm so glad I chose to be a stay at home mom.
Everything is a learning experience-- things change. There's no handbook or manual for life, and that there's no right or wrong way to live your life. And that thing we call 'living life' is just making it up as you go.
