Or am I assuming too much and you are a single parent?
But kids grow up - it doesn't stay this way forever.
I recall my SO asking my relative's wife (mother of three) what to do if you're already out of energy and dinner is not ready.
"Some days there just won't be any dinner for you" was the reply.
I'm not a parent though (although planning to be), so am keen to know why that's wrong.
The only wrong approaches I can identify is beating yourself up about not preparing a decent meal for yourself and not eating at all.
Both me and my SO lost weight in the first months because we made the former mistake.

Thank you for saying this. I strongly believe this is the right action until kids are older and start helping around the house. (Still trying to convince my SO though.)
Honestly, raising kids is not that hard if you give yourself permission to be not perfect. Order pizza, avoid using plates when you can, let yard overgrow a bit, hire cleaning service. Bail out of unwanted social obligations. In fact, trying to get approval of others is what makes parenting hard.
