I also don't believe in the scheduled feedings, DS is 3 months old, and is still fed on demand. For the first 6 weeks I felt like I was constantly feeding him. And as far as how you get thru it.......it's very simple.......you just do!! You said it yourself "the Laundry can wait", SO can the cleaning, thank you cards, etc.
During the day my little guy will sometimes only go 2 hours, sometimes 4. But at night he goes to bed at 8pm and wakes at 5am for a bottle then back to sleep untill 745am. The best thing I did was start him on a bedtime routine from the start.....I call it the three B's Bath, Bottle,Bed. We put on Jammies and play music. He even puts himself to sleep, as I put him in his crib awake. So hang in there before you know it he'll be going longer, and then you can do the laundry.....
