I feel ya, OP. While I do like my crockpot, I either need to set it for 11 hours or trust that DH will turn it on when HE leaves... so I tend to not use it during the week
-If the issue is clingy-child, and I get that, try meals that don't require "stand here and stir and add a bunch of stuff." Things that you can just throw in a (still preheating) oven and then go get 40 mins later. Such as: chicken, small potatoes, and carrots - pork chops and roasted cauliflower - pasta bake (1 box pasta + jar sauce + water + foil over the top) - etc. She can screech for 10 secs while you remove the dish from the oven later.
-Can you wear her on your back (ergo or such)? For short periods, provided she can't reach around and grab stuff. I have also done this specifically so that I could take something out of a hot oven without my kid slamming their hands down on the oven door.
-Double duty meals. Roast a chicken on Sunday? Roast TWO. Then use leftovers to make other stuff like chicken salad or pasta. Freeze extras, your freezer is your friend.
-If your issue with the crockpot is that it's running unsupervised, could you run it at night? Unplug in the AM and stick the insert in the fridge (lay down a hot pad). Spoon out and reheat at dinner. Similarly, I have roasted chickens at NIGHT, and just planned to serve cold roast chicken and/or leftovers. Stick chicken in oven, turn on, go upstairs for bath/bed/whatever. Come back downstairs, drink a glass of wine, pull chickens from the oven. Beautiful (and it makes me feel SO on top of my game).
-Super simple dinners. Some people will disagree, but the occasional dinner of cheese, crackers, and fruit - or scrambled eggs, sliced tomatoes, and toast - or cold cereal and fruit - will not kill anyone.
