I found after you have Cheese the crops are irrelevant. Just go Milk and Cheese, Crops are just extra. Assign each girl 4 days a week, every girl has different days off and 2 rotations of cheese. I put the cheese 4 days apart. You always have cheese cooking, and you get about $100 of milk money a day
Also, if you milk Aurora manually, the skip button remains in the upper corner. Pressing it lets you actually get her milk twice. I agree cheese is op, but maxed radish is also nothing to sneeze at. You can very easily cover all of your expenses using radish only. The cheese ontop of that is nice. I usually harvest, plant then milk the people. I know you can go to the lake to skip time and make them fill up more, but I don't usually bother. It is enough to keep the 2 cheese going. Milk money by itself is not bad, but not really worth the trouble. Max radish is like 4 taps and 3 seconds a day for a flat 300 dollars, meaning you make 2100 dollars per week. Of which you need to pay 200, the rest you keep for yourself. Add to that cheese money, and that is an extra 250 dollars per day. The milk money not really worth it for that 200 something daily, just make enough for cheese.
