I disagree. DS was a catnapper and i refused to 'just go with it' as he very clearly needed more sleep. I think if they're bright eyed and bushy tailed on catnaps, then that's probably just in their nature and there's nothing you can do, but if they need more sleep you can teach/help them. I used Jo Ryan's babybliss technique and it worked a charm (although it took a lot of work)
I get a bit stabby when people say 'just go with a catnapper' I started a thread about it the other week.
It's totally possible to learn to sleep better, if you're not sleeping well. I'm a pretty terrible sleeper myself, but i know if I stick to regular bedtimes, don't sleep too much, and use relaxation techniques I get much better sleep.
ETA that article is from a pro CIO website. So... I'll be taking that article with a grain of salt.
