We need help! I have a 3 week old infant who will only fall asleep when held. The swing doesn't work, and if we sit down, he wakes up! DH and I spend an hour and a half rocking him back to sleep during the night, and we're exhausted as he wakes every 3 hours to feed. He's too little for CIO. What should we do?!?! He's currently sleeping in the rnp, but we are switching to crib in a week.
