Various Advantages to carry in Piggy-back position! Safety Support enables you to enjoy piggy-back carrying position in safe!

There are lots of benefits to carrying in piggy-back position. However, some people do not feel comfortable because their baby has to go on their back and they cannot see him/her. "Safety support" prevents their baby from falling down. So, it is very easy even for a new mother or father to carry their baby on their back.

Very easy to set up.

Why piggy-back position is good?

  • Good visibility

    There is no obstacle to cut off parent's view. Your field of view become narrow when you carry in face-to-face position because baby's head comes to just diagonally downward of your face.
  • Both hands free

    You can use both hands. It is very helpful for busy parents.
  • Develop babies sense of balance

    Babies can look not only up and down but also left and right at the same time as mother moves.
    Babies also feel mother's movement through their body.
    This is very good to develop baby's sense of balance.
  • Prevent babies from constipation

    Babies can move in accordance with mother's movement.
    It makes the movement of baby's bowels more active.
  • Reduce Strain on parents

    It reduces a strain on parents from the skelton structure point. When you carry in piggy-back position, you use back muscle more than abdominal muscle. On the other hand, when you carry in face-to-face position, you use abdominal muscle more than back muscle. Because back muscle is larger and stronger than abdominal muscle, you feel much comfortable when you carry in piggy-back carrying position.

ATTENTION! Point to Notice!

The position of the backbone when you carry in piggy-back position
Baby's backbone aligns mother's backbone.
Baby's backbone does not align mother's backbone.
Therefore, babies tend to throw their head back, and mothers feel hard.

Considering to carry in piggy-back position, conventional type baby carrier(No waist belt type) allows you to carry your baby in high position. In this case, baby's backbone aligns mother's backbone. You can comfortably carry your baby. On the other hand, when you use waist belt type baby carrier, the carrying position automatically becomes much lower because it fixes baby's position on the waist. Therefore, baby's backbone does not align mother's backbone, and makes it easy for babies to throw their head back risking injury.

Side Plus firmly supports baby's head, neck and back with head and back support board and sleeping support. They work well for retroflexion to all direction which is not only to the back but also to the left and right.

※Please refer Point 3


Lucky's special function Head-and-Back Support Board firmly supports baby's neck and back. Even new parents can ensure enough safety and easily carry their babies in piggy-back position.
Carry in under-arm position

The most important point when you carry a newborn baby is to support his/her neck. Carrying in under-arm position is highly recommended for newborn babies because this position makes it possible to support coggling baby's neck. If you carry in vertical position, the baby receives lots of strain on his/her neck because of your movement. For example, when you walk, baby's body also moves up and down. This movement gives a strain on baby's neck.The under-arm position also keeps 45 degree angle, so you can carry your baby like a bouncer. Besides, dislocation of the hip joint is one of the worries for newborn babies. Side Plus reduces a pressure on baby's hip joint.It's because the head-and-back support board and moderately soft waist belt part ensure enough space so that baby can move their legs freely.This structure prevents babies receiving the pressure from both sides unlike sling. Under-arm position & Head-and-back support board firmly supports baby's neck and back.
