Skipped nap so I let her sleep longer?

[Momhope15]

My almost 6 weeks old DD missed her morning nap being 4 hours awake in the morning.
She was up at 7 and only went to sleep at 11am.
She has not been asleep for over 2 hours - do I wake her or let her sleep?

I never woke DD from a nap other than if it was late evening for a feed and change before bed. She hardly napped though in comparison to most babies. Even now at 13 months I only ever wake her if she's already had a good long nap and it's time for dinner (which we eat around 6pm).
