It pisses me off to no end how people don't respect my child's sleep routine.
It's a natural routine that her body created.
If she doesn't have a nap, she needs to be in bed by 7pm or she misses her sweet sleep spot.
The sweet spot is the time period before a kid is overtired and thus becomes wired.
Once you have a kid who is overtired you get a child that's too tired to sleep. He/she starts playing and using her/his smarts to avoid sleep.
