when I move you move, just like that ...

My baby is such the heat seeker, all night we do this dance where I scoot over and he scoots over until finds me or the fusses for the boob. It is really quite predictable. I wake up and notice that he is practically getting smooched by me so I move over and he instantly stirs to get near me. I don't know how he can be in a deep sleep and feel me the instant I turn. It is truly unreal. I really have no issues with co-sleeping and find that on most nights it works but some nights man he really has me worried. I worry that he is not getting a good night's sleep and I also worry that he will be in our bed when he gets to high school! Are sleep interrupted nights the trade off for the happy little man that I get during the day...if so I will take it!
