Mine first 2 are 17 mos apart and I still can't figure out how I managed. My little girl would climb up on the couch with her baby while I nursed my boy. She was so eager to help and would bring me diapers and toys and blankies. The toughest part was getting them to nap at the same time, but once you accomplish that, it's a breeze. Don't forget that you get a 2 day vacation (read: hospital stay) to start you off. In fact, that's what I looked forward to most when I had my second and third. Just tell all the people who remind you how tired you will be that you're already exhausted. At least when the baby comes you'll actually fall asleep when you lie down.
