What are the red flags beginners miss in Parenting?

My current rule is simple: if it takes less than 5 minutes to prepare, I am much more likely to keep doing it.

Context: I am not an expert, just someone trying to make Parenting feel less intimidating. I wrote down what worked, what felt awkward, and what I would do differently next time.

Would love to hear how other people handle this. I am especially curious about the version that works on a tired weekday, not just on an ideal Sunday.
