We did co sleep for a little while. We only stopped recently when Claire started moving around and crawling. I was worried she'd crawl out of our bed and hurt herself. I just put her in her cot and she sleeps fine. She still wakes up overnight, but she did that when we were co-sleeping anyway. Just do what works for you.. You'll probably get comments from the people who dont uderstand, but dont feel like you have to jusitify yourself. Pinky Mckay has some good books - I've got Sleeping like a baby. It has some good info on co-sleeping and also just baby sleeping in general.
