DD never napped much or regularly -- she forced herself to stay awake so she wouldn't miss anything. She slept deep when she slept, but she never slept through the night either. And I mean never... eventually she just got old enough to get herself a snack, go to the bathroom, read or hang out in the middle of the night without our help so at least we could finally get some sleep. She also had terrible colic, night terrors, and sleepwalking issues over the years.
There's a reason she's an only child.
