Our son slept in a bassinet until he was 6 weeks old next to our bed. A few times in the first 6 weeks I would have to hold him. He is adopted and came with a few issues so having him sleep on me helped soothe him, again I did this less than a handful of times. He went into his crib at 6 weeks and started sleeping through the night at about 12 weeks old. Even now that he is almost a year I don't like to sleep with him. My husband will sometimes take a nap with him and I tell him I don't want him to get use to it.
