My 6 week old usually sleeps in a bassinet beside our bed, and he wakes up about every 3 hours during the night to be fed. However, when my husband has 3rd shift I sometimes pull him into bed with me to make night nursing easier. My question is this: when he is sleeping beside me it is like he has been drugged or something! He normally wakes up every 3 hours, but when in our bed he sleeps a lot longer. The other night it was 5 hours; I was pretty freaked out when I woke up and realized how long we had been asleep. He seems fine otherwise, so I'm not too worried, but I was wondering if this is a common phenomenon?
