Many of the hard baby carriers, when the baby is positioned with the legs unsupported and hanging down, place too much stress on the spine. Most doctors do not recommend this position for infants, especially not for more than a couple of hours at a time. The design of the Boba Baby Wrap ensures that there are no pressure points on your baby. Your baby’s legs, hips and spine are supported. There is no limited length of time that your baby may spend in the wrap. You may carry your baby all day long if you wish with no harm to your baby’s developing body.
