COMPLETE™ Ergonomics

 The COMPLETE™ adjusts to provide ergonomic leg positioning in every carrying setting, including the face forward position.


The líllébaby® COMPLETE™ baby carrier was designed with baby’s healthy hip development in mind. Its features are recommended by the Hip Dysplasia Institute and specialists, including adjusting to baby’s size(1) and allowing baby’s feet to spread naturally apart in a frog-leg position(2) in every carrying position.

Adjusts to Baby’s Size

According to experts (1) it is important to choose products that adjust to baby’s size. The líllébaby® COMPLETETM seat adjusts to facilitate a natural frog-leg position for infants and provide the right support as your baby grows. You can also carry your baby in a fetal position during the first few months. The unique patent pending seat design adjusts to baby’s size and allows for ergonomic spread-leg support in every carrying position, including the forward-facing position

With every carrying position available, you can choose the position that is right for your baby’s age and size.

Preventing Developmental Hip Dysplasia (DHD)

According to specialists, babies may be at risk of developing hip dysplasia during the first 5-6 months of life(3).  To prevent hip dysplasia and hip dislocation, babies' legs should be in a natural position with the ability to move the legs freely.

During the first 6 months:

  • Avoid forcing baby’s legs together like swaddling or by carrying a baby “hanging” by the crotch
  • Avoid forcing baby’s legs too wide

Baby’s legs should be naturally spread apart, never forced. In the líllébaby® COMPLETE™ baby’s legs are naturally spread apart in every setting. It adjusts to baby's size since most babies are not ready for the "wrap-around" position until they are 6 months.

Naturally spread apart = not forced closed and not forced wide.

(1) “The healthiest position for the hips is for the hips to fall or spread (naturally) apart to the side” - Hip Dysplasia Institute

(3) “The risk of hip dysplasia or dislocation is greatest in the first few months of life. By six months of age, most babies have nearly doubled in size, the hips are more developed and the ligaments are stronger, so are less susceptible to developing hip dysplasia”- Hip Dysplasia Institute
