Yes, wearing your baby can be an essential asset for a new mom. Baby is close, feels secure and mom can have her arms free to eat or even brush her hair.
When babies are born, they have a "C" shaped spine and a round head. Time spent laying flat on their backs in cribs, bassinets, car seats, swings, bouncer...you name it, put undue pressure on delicate hip joints and can sometimes lead to flattening of baby's skull. And in these times of the "Back to Sleep" campaign and portable baby car seat that will go from house to car to stroller to shopping cart, baby spends loads of time on it's back.
However, you can help lessen that amount of time by wearing your baby at home and out. You can get stuff done at home while baby is in a carrier either on your front or back. You can wear baby through the grocery store or mall. It will also keep baby close, calm and easy to nurse.
I do NOT recommend a Baby Bjorn or any of the "Crotch Dangler" carriers, they too put stress on the baby's hips and spine.
These are some great carriers to try out:
ONLY the Mei Tai and Ergo can be used on the back. And ALL of them are ok for baby's hips and back.
