If your baby hated naps or just didn't nap well, did it ever get better? When? How?

My 6 month old has never been a great napper. She has always slept awesome at night, mostly sleeping through the night by 6 weeks. So I haven't been super concerned about the napping. But this week has been an all time low in the nap department, and I'm starting to lose my mind. Her best nap day of the week was yesterday. She woke up for the day at 7:30, took a 5 minute nap at 1pm, and a 50 minute long nap at 3pm. She didn't go to bed until 9pm. The worst day of the week, she was up from 5:50 am til 8 pm with only 25 minutes of nap time throughout the day. Please tell me this will get better.
