Some Soylentils have managed to reproduce, so this study, which has findings on how to keep the young ones keep sleeping through the night, might be useful.
Overall, studies indicate that 15 to 20 percent of one to three year olds continue to have nightwakings. According to Stephanie Zandieh, M.D., Director, Pediatric Sleep Disorders and Apnea Center, The Valley Hospital, "Inappropriate sleep associations are the primary cause of frequent nightwakings. Sleep associations are those conditions that are habitually present at the time of sleep onset and in the presence of which the infant or child has learned to fall asleep. These same conditions are then required in order for the infant or child to fall back to sleep following periodic normal nighttime arousals."
Sleep associations can be appropriate (e.g., thumb sucking) or problematic (e.g., rocking, nursing, parental presence). "Problematic sleep associations are those that require parental intervention and thus cannot be reestablished independently by the child upon awakening during the night," adds Dr. Zandieh.
Here are some helpful tips to help your child sleep through the night:
Every child is different, but the techniques seem sensible and worth trying, such as giving them a security blanket (or teddy bear, etc) when being put to bed to signal it's time to sleep.

I've tried and failed at polyphasic sleep a few times (mostly uberman, but also everyman and dymaxion), and had the following effects from the experience:
I discovered I was actually prone to dreaming that I was lying awake.
I learned how to fall asleep much more quickly and easily, and even to nap.
My understanding and experience of sleep in general changed for the better.
I know it's an odd and radical suggestion, but trying to subsist on a sparse and entirely nap-based schedule for a couple weeks or longer can really teach you a lot about the nature of sleep and totally recalibrate something in your brain/body, even if you probably won't succeed at (or don't intend) adapting to the pattern long-term (or even get beyond 3 to 5 days without passing out for 3+ hours at some point).
But regardless of tactic, if you actually give yourself good /practice/ at sleep somehow, you can actually get better at it.
