I've tried everything except wrapping DD (now 7 months - she hates being wrapped), and she still catnaps most daytime naps. One exception is when her dad sleeps with her - that seems to keep her out - maybe the sound of his snoring?

But she's happy. I stopped worrying that she wasn't getting enough sleep months ago, because she seems fine. Very calm and cheerful.

It does make for a harder day for me, though...
