I have been swaddling my 2 month old from day one at night. It seems that it is the only way she will go to sleep or calm her...flailing arms etc. She is kicking more and becomes unswaddled at times during the night. I just happened to run across a comment in the "what to expect the first year book" that you shouldn't swaddle past 1 month because it can cause developmental delays. Now I am worried. Has anyone read this and what age should swaddling be stopped if not?
