I had ds1 in UK and never swaddled as I got the impression that it can be unsafe due to baby overheating and it's not great for hips. Also I was worried about getting into a habit that might be hard to break. However over here I seem to see people mentioning it quite a lot and have seen a few ready made swaddles in shops. Just wanted some thoughts and ideas as to whether it's safe, does it work and why and if so which brands would you recommend? Am currently 31 weeks pregnant so willing to try with ds2 if it might be useful.
