I think the theory of raising children differs a bit from the reality of it.
Try to picture this. You've just worked a full day. You frantically rushed everything at work and left before most of your colleagues, just to get out in time to collect your kids. Lateness would have cost £1/min. Having achieved that objective, you get home. It's 6pm. Kids are hungry and arguing. You choose to solve the hunger problem as a priority, so you balance cooking (super healthy organic meal, of course) whilst trying to stop world war 3. Then you remember the kids have PE tomorrow and no clean clothes, so you get some washing on. After having got some food on the table, cleaned up, hung the clothes, checked your emails, got the kids to do their 20 mins of reading a day, run a bath, worked out how to survive tomorrow, sat down for the first time at 9pm, your 10 year old daughter announces there's this exciting discussion at school tomorrow, all she needs to know is her three finest skills. Of course, some parents will magic up a free 30 mins to explore and play with their brains - others will just think what three things will solve this problem, keep their daughter happy and let her participate at school. Then they can move on to the next problem that needs solving.
