Hi K.!
How wonderful to hear from a new mother who has learned the joys (and restfulness) of having your little precious one with you all night long!! You have learned that your baby's need to have you close does not go away when the sun goes down :o)
Did you know that, in spite of the AAP's recomendation to have your baby sleep in his own bed, that 80% of Western parents have their babies in bed with them for some portion of the night. In the rest of the world, it is the norm!
I will share what we did, but remember that you must do what works best for your family and your baby.
While our babies were little, they were never out of my sight. They slept naps in a portable crib in the family room so I could constantly check on them or in my arms, in a sling, etc., and they slept the night in our bed, next to me, their breastfeeding mother. Once they were old enough for me to be okay with them being out of my sight, about 4 months, then I would put them down for naps in their cribs. This way they woke up in their rooms and learned that this was a happy place to wake. I always responded to their early fussing - I wanted to let them know that I was going to be there to meet their needs.
At night, they slept with us until they were crawling, around 6 months (when safety became an issue). I would then nurse them to sleep (perfectly natural thing to do, btw) and lay them in their crib. That would allow a little bit of time in the evening to take a breather, talk to my husband, etc.. When they would wake for the first time, I would bring them to bed and they would stay there the rest of the night. Whether that was 1 hour or 5, that is what we did. For some reason this kept them from crawling off the bed. It was at that first waking that they seemed most active. So, if they did that first waking in their crib, then they didn't seem to crawl anymore the rest of the night. I don't know why.
As they grew, over the next couple of years, they would sleep longer and longer stretches in their rooms. Of course, there were times when they slept with us more. Babies' needs will ebb and flow like the tide. There were lots of nights when they wouldn't come in until 4 or 5 in the morning, and we would nurse and cuddle and sleep until 7 or so.
Eventually, they would sleep the whole night in their rooms. This didn't happen until they were in a toddler bed - which was great because then they could get up and come in on their own! We always welcomed them into our bed whenever they wanted to come. Each of them stopped coming in at different ages, around 4ish, I think. Now they are 7 and 9 years old. They don't want to sleep with us anymore. :o(
A few weeks ago, our daughter (7) slept 3 nights with us ( I don't know why, she just needed to). My husband and I just relished those fleeting moments with her!!
Their babyhood is hard, exhausting, and seems long, but it will be over before you know it, and you will be longing for those nighttime cuddles! I have to beg my son for a hug these days, but he still holds my hand! I am hanging on for dear life to those little things, I know they are growing up! Enjoy their littleness, their need for you, and all the cuddling that they need - even at night!
Here are some resources. James McKenna is a medical anthropologist whose research has focused on sleep sharing around the world. He has a sleep lab where he studies the benefits of shared sleep between mothers and infants/children.
His book is "Sleeping With Your Baby: A Parent's Guide to Cosleeping", James J. McKenna, Ph.D.
