The negative on swaddling and cosleeping is that it reduces bubs ability to alert you if they need, it is also less important when mum is right there to cuddle them. But their arms are so jerky at first and movement is involuntary, so I did swaddle dd and cosleep in the early weeks. Seriously you're so hyper aware if them in the bed and swaddling stops their arms waking them up. I also swaddled for each feed because her arms would get in the way.

We stopped swaddling by 12 weeks.
