Craka I have bad news for you. You should mentally prepare for NEVER SLEEPING MORE THAN TWO HOURS IN A ROW EVER AGAIN
Yeah I'm okay with that (and it's been that way since he was born). I just shoot for a full sleep cycle of around 1.5 hours, wake up, change his diaper. Wife puts him on the tit, and then I supplement with formula til he's in another coma for 2 hours.
My wife and I were so exhausted we went to bed around 11pm yesterday, didn't even bust open the "champagne" (sparkling wine...not paying more than $15 for a bottle of champagne)
