Not that I expect everyone to do it, but we ate MREs sometimes while my then-husband was in the Army so that I could be home with our daughter. My husband got the meat stuff (I’m vegan), I ate the vegetables and grains. Rice with soy sauce and pepper was my dinner some nights. The baby got her baby food and some.
Never regretted a day of it.
You did what real parents do. Although most of us eat meat LOL - just kidding on that one.
Talking to my nephew I asked him if he would take a bullet for his kids. He said unquestionably. I said, you’re a father.
