I have a 3 and a half month old DD who still wakes frequently, and for me it's coffee chocolate and spending money that helps me get through the lack of sleep. I didn't even like coffee three and a half months ago 
I'm still searching for that magic berry that wakes me up instantly and gives me lots of natural energy for the day, but no such luck!
What gets you through the sleep deprivation? Even if it's just the internet at 3am, (i'd go mad without it) i'm interested to know, and if any of you have any suggestions on good sources of natural energy please share
