That's pretty much what I do now. My daughter (at one!) still needs a bottle around 2-3 am, so I'll feed her then tidy up or move the wash to the dryer or something. I think it's at least worthwhile to explore how you sleep, even if you're not trying to do the whole polyphasic thing. Just sleeping at a regular time every day, and timing your wakeups to coincide with a sleep cycle can make you feel better and give you a lot of extra hours on the weekend (no sleeping in!)

Napping in the afternoon (the hottest part of the day) is common in many cultures as well.
