We know there are only 3 trimesters of pregnancy, but many top doctors, scientists, and psychologists, agree that a fourth trimester occurs outside the womb once baby is born. This busy, and somewhat intimidating, transitional period is a great opportunity for babywearing to truly shine! You can achieve skin to skin contact, breastfeeding on demand and establish bonding- all from the convenient hands-free use of a baby carrier. As an attachment parenting follower, Newborn Babywearing in the fourth trimester was wonderful for me.
