I have five kids, never went without necessities, and never had half that monthly budget.
I don’t know what you are buying but wow! Maybe you have huge medical conditions bills or something.
Same here with six kids. I’m often amazed at God’s provision. Then other times I pout over my ugly house, old vehicle, etc. But those times are getting fewer as I realize how short the time is with my kids at home. Oldest has grown up and moved out, next one will be gone soon.
