I've finally got round to buying a swaddling wrap to try on my little one when he decides to make an appearance. My questions are. It seems very thin, which is probably a good thing, but will I need an extra thin sheet or blanket over him to keep him warm in addition to his sleepsuit, or should I just put sleepsuit on with wrap and see if he settles without any extra covers first. Also, have any of you swaddled your baby using just a sheet or a blanket, and what did you use? I saw a video the other day of how to swaddle a baby but she wasn't very specific about the material she used or whether the baby would need any other covers. What is your experience with swaddling?
