When we were on vacation, everything seemed to click. I don't know exactly what it was. We thought it was that the babies were so worn out from watching the "big kids" all day, but it has been consistent and even better since we've been home. We thought it was THE swing (a big swing rather than our little travel ones) that our friends gave us (they had a similar sleeper to Ryan and THE swing helped her), but we have been "practicing" having him not sleep in THE swing and 9 out of 10 times he falls asleep easily in his basinette.
Now, I lay them down for bed, or their naps and they fuss. Sometimes they cry hard, but never for long. Usually, within 5 minutes it's silent. Sometimes longer, but almost never longer than 15 minutes. If it is longer than 15 minutes it's always only one baby. If it's Ryan I put him in his swing (because he cannot settle down when you try to rock him to sleep), and he's out within 5 minutes. If it's Allie I take her and rock her (because she cannot settle down in the swing) and she's out within 5 minutes! For naps they sleep 45-90 minutes consistently and occasionally 2 hrs. At night they almost always sleep at least 8 hours - it is a rare occassion when one of them sleeps less. Almost every night one of them sleeps 10 hours (but not always the same one every night). And a few times both have them have slept the ENTIRE night (11 hours!)!!!
I don't know what has brought about the change, but we are loving it! I can finally get things done during the day, and the sleep at night has made Lucas and I entirely different people. I know things will probably change once they start teething and there will be the ocassional sickness that will throw everything into a tailspin, but we're fully enjoying the sleep for now!
