If possible, have your partner hold baby while you wiggle into front pack straps.
The front facing baby position is a more advanced position for baby, and is designed for a baby who has good head control (can lift head up and maintain position). When baby is first born, you will need to place baby in front pack so his/her tummy touches yours.
A front pack may be used until baby reaches about 14 pounds. At this time, you will need to transition him/her to a backpack (only if your child has good head control), or a baby stroller.
When you become fatigued, shoulders will start to droop. This will be your key to finish your walk.
