My friend, my sister, let’s discover, step by step, how to use a wrap baby carrier (I am using a Didymos wrap in organic coton). Baby will be able to snuggle safely on our heart with this knot. It is suitable for newborns and toddlers. Once baby develops strength in holding her head, you can choose to leave her arms outside the wrap. For small babies, I advise leaving her arms inside for better support. Always make sure her knees are higher than her bottom, in a nice froggy posture.
