Just had a wonderful parent moment - walked into the bedroom and found my wife and my son asleep together, nose-to-nose. My heart melted! There really isn't anything more beautiful than that: my life partner and best friend, dozing happily with a comfortable, happy little baby. I snuck in and took a picture, because I just had to memorialize the moment.
We've been doing a lot of co-sleeping / family bed stuff lately. Not intentionally: what happens is, one of us goes to get him for his 2 / 3 / 4 AM feeding (whenever he wakes), brings him inside, and then everyone falls asleep mid-feeding. I honestly don't mind that; I think I'm worried about breaking him into spending the entire night in his bed, but that's not a huge concern right now. (Remind me of that when I'm not sleeping because of it!) I enjoy having the boy there with us, because it makes me feel better. It obviously makes him feel immensely more comfortable - the look on his face when he wakes up and sees Mommy on one side and Daddy on the other side tells it all.
It does cramp things a little bit, though. We don't have any specialized sleeper-type thing with us, so I'm a little afraid of the whole SIDS thing. God forbid, the blankets get pulled up too high... although, I have been training him in the "Where's the baby?" game. He's pretty good at pulling sheets / towels / diapers (clean) / washclothes off of his face to reveal a smiling, giggling baby whenever I ask the question! But, for the most part, we sleep with the blankets a lot lower than we're used to sleeping, which is why The Wife now sleeps in a sweatshirt. It doesn't bother me, because I handle cold a lot better than she does.
I do think that the sort-of-co-sleeping that we're doing is giving us an extra hour's worth of sleep on the weekends, for sure. It's making the weekdays a little bit easier, also. Plus, it's hard to get cheesed off at a smiling, happy baby who's snuggling up to you when he wakes.
