As your baby grows and gets heavier you can change to a back carry like for example the Rucksack Carry which will be more ergonomic for you and your child will enjoy the view from this more open position. It is a very comfortable carry for both adult and child when you go for outdoor hikes or long walks. If you use a size 4 wrap it will be comfortable to bring the wrap ends to your front where you tie them with a knot
The Rucksack Carry is suited as soon as your child is able to hold the head up unassisted and steady. If you want to wear a smaller baby on your back we recommend the following Back Carry.
Position: on the back
Age: from 4 or 5 months on when your child is able to hold the head up steady
Wrap Length: size 3 or 4 and longer
