With some women the water breaks, and then they begin to have contractions. In the first stage of labor, the cervix will dilate from closed, which is its normal state, to fully open at 10 cm in diameter. In mothers having their first child, this stage usually lasts 12 to 16 hours. For women having second or subsequent children, the first stage lasts around 6 to 7 hours.
Umbilical Cord Care. After the umbilical cord is cut at birth, a stump of tissue remains attached to your baby's belly button (navel). The stump gradually dries and shrivels until it falls off, usually 1 to 2 weeks after birth. It is important that you keep the umbilical cord stump and surrounding skin clean and dry.
Okay, the trunk incurvation is also called the galant reflex. If your baby is on his stomach and you stroke neck to the spinal cord (paravertebral area) on his middle to lower back, it will cause his back to curve towards the side that you are stroking. This reflex is present at birth and disappears by 3-6 months.
