The normal baby may be slightly bluish in the extremities a short while after birth but becomes pink within a few hours.
Urine is passed during birth or immediately after birth, but a vast majority passes urine within the 24 hours.
The first stool, which the baby passes, is known as meconium, it is black in color and is paste like. Meconium is passes within the first day and the stools change to golden brown over the next 2 – 3 days.
