Both my two had a similar routine to saddlebag. But DS kept his afternoon nap until he was four and a half. DD dropped hers at eighteen months! But instead of letting her stay up, I'd still put her down for a nap, usually with some soothing music and cuddly toys, for about an hour in the early afternoon. Otherwise she was completely feral by six pm! She didn't sleep during her nap, but she did unwind and chill out and it seemed to be enough for her.
That said, DD has slept pretty well at night since about two years old, DS is still a super light sleeper who struggles with going to sleep. He is like me. We just can't switch off. And if we've had a day full of new experiences, we struggle to fall asleep, then we dream/talk in our sleep and wake up several times a night and then struggle getting back to sleep! And when we are like this, any little thing can make it super hard to sleep; uncomfortable bed, wrong pillow, too much light, full moon, too hot, too cold, aching legs, thirsty, hungry, etc You get the picture.
Maybe this is similar to your little one? She is over stimulated, and can't switch off?
Things that I've found help? Rescue remedy, relaxation and meditation exercises, soft slow instrumental music, eliminating any extra probs like hunger, thirst, aches and pains etc
Hope you figure it out
