Context: Tonight was the first time that Sage went to sleep in her crib . She 's slept there before , but only when put down while already sleeping . It took a lot of patience and intervention , but we had tried it before * to see whether it would be easy , but without much commitment because it did n't matter much , and since it had n't worked we usually picked her up again and brought her to the bassinet in our bedroom . Also had a marvelous visit by some old college friends , who came to Rochester to spend some time with us and see the new baby . It was a good weekend , and a pleasant way to spend Father 's Day ( admittedly , not a holiday I take very seriously ) .
