The one that seems the most natural and adapted to your baby and your daily life!
Your baby is rather light and you only need an occasional carrying device, to go from the car to the nursery or to run a small errand? You can still opt for a Little Wrap Without A Knot.
Worn in a sideways sitting position, your baby will be able to see what is going on around you and share your facial expressions. If you are more into long walks and your baby weighs a lot, a baby wrap or a full-buckle baby carrier will distribute the load on your body better and will be more adaptable to side or back positions in a few months.
