interrupt too long naps?

When your baby has a tough night and then the first nap of the day is super long, do you wake them up?  It seems so unnatural to wake her up, but baby girl is going through some sleep issues the past week or so and I'm starting to wonder if I could do things differently to right the ship! But then again, I know good daytime sleep is predictive of nighttime sooo...yeah...just hoping this is a short-term growth spurt thing!
