Exercise 13
Childbirth, part 1. There is some concern that if a woman has an epidural to reduce pain during childbirth, the drug can get into the baby’s bloodstream, making the baby sleepier and less willing to breastfeed. In December 2006, the International Breastfeeding Journal published results of a study conducted at Sydney University. Researchers followed up on 1178 births, noting whether the mother had an epidural and whether the baby was still nursing after 6 months. Below are their results.
a) What kind of test would be appropriate?
