It’s normal and very common for babies to fuss when they are being transferred from one place to another, including when putting them into a baby carrier or wrap. Tired babies are also more likely to fuss in a sling, but stick with it! Give it 5-10 mins of movement and they’re very likely to settle and/or fall asleep.  Walking, especially outside in fresh air, is a great way to settle your baby. If not then take a break to feed, play, relax and try again later. If your newborn is hungry then they’ll be unlikely to settle in your wrap or carrier, especially if they’re breastfed, as they can smell your milk but can’t get to it! Even if they recently fed, try offering an extra feed.
