I miss co-sleeping. There was just something about having my little guy wrapped in my arms every night that was indescribably special. I got to cuddle with him all night long. I felt every breath he took. And we woke up together in the morning looking into each others eyes.
And I miss nursing. We both got it right away, it was always easy for us. He did wean himself pretty early though. He was six or seven months old when he lost interest. It was natural at the beginning though. He didn't want to nurse immediately after being born, and I was a little worried at first. But within an hour or two he was nursing like a pro. Moms and soon to be moms of the world, take note, breastfeeding is one of the most amazing, intimate things you can do with your newborn. I know that it isn't politically correct to say breastfeeding is better, but having done both I think it is.
Breastfeeding and co-sleeping facilitate each other as well. Middle of the night feedings didn't require either of us to really wake-up, and the first feeding of the day usually turned into the first nap of the day and I got to sleep in quite a bit. And he was so small then. He couldn't even roll over consistently, much less crawl off the bed. Now he moves around in his sleep too much to share with me. And he's not much of a cuddler. I hope he will like cuddling eventually.
I think the right answer to breastfeeding and co-sleeping is whatever best suits you, but I think it's safe to say that you can enjoy both for as long as you want, but especially early on, without it affecting you or baby long term. My son gave up the pacifier on his own around the same time too. Maybe I'm just lucky.
