On another note regarding pharmaceuticals for making it through a day like that, Modafinil works wonders without the jitters that come with caffeine overloads. That being said, if you've got a two year old I'd think that your sleep schedule will mostly be customized with some daily exercise, avoiding bright screens at night, and supplementing with some melatonin. If you do, I'd advise to try lower doses of melatonin, as lots of times lower doses work better.
