To nap or not to nap, that is the question...

Yesterday, Lauren napped for about 45 minutes, and I might be exaggerating on how long she actually slept. Therefore, last night she slept, no exageration, 12 hours with two brief periods of cry, cry, cry go back to sleep in the middle. So, today she didn't nap until 3 p.m. What kind of crazy nighttime schedule will she be on tonight? I know she still needs naps. I know that, most of the time, she still wants naps. Why, then, does it take every ounce of brute strength she has to keep herself awake and screaming, instead of peacefully giving into sleep like I would?
