@artg Take a breath. As a working mom with an autoimmune condition, I have to be very careful on how I use my spoons. Spoon theory:

Anyway, most nights, my SO and I will discuss if he's cooking, I'm cooking, or we order out. I know that's not what the perfect parenting books tell you, but the fact is that we can only do so much.
Cleaning? Hahahahaha. I straighten up, of course, but hard-core cleaning on a weekly basis? Yeah... that's not happening.
I would recommend that you and your husband have a conversation about making adjustments to the current arrangement. Maybe you switch off cooking each day. Maybe you take turns with each child each day: for example, on Monday your husband spends 15 minutes with your older child, and you spend that 15 minutes with your younger child, on Tuesday you switch, and you go back and forth. Divide and conquer. You know?
Hire cleaning people (if you can afford it). Try to meal prep on the weekends to make daily cooking easier.
And go easy on yourself. You only have so many spoons.
