I want to talk a little bit about the 4th trimester and how important this time is for baby. The 4th trimester is the month of life after baby is born. It is named this to be perceived as an extension to the third trimester in the womb, where baby is still developing. Many parents bring their sweet newborns home, not knowing much about this tiny little human or how important the first 4 weeks are adjusting to this brand new outside world.
