At first papyrus was only used in Egypt, but by about 1000 BC people all over West Asia began buying papyrus from Egypt and using it, since it was much more convenient than clay tablets (less breakable, and not as heavy!). People made papyrus in small sheets and then glued the sheets together to make big pieces.
Your baby's first poo is called meconium. This is sticky and greenish-black. Some babies may do this kind of poo during or after birth, or some time in the first 48 hours. After a few days the poo will change to a yellow or mustard colour.
What is meconium aspiration? Meconium aspiration occurs when a baby breathes in amniotic fluid containing meconium (the baby's first stools). Before or during labor, the fetus sometimes passes the meconium stool into the amniotic fluid. It is not clearly understood why this happens. It may be a natural event, but it is also thought to be related to fetal distress in some babies.
