From www.medsafe.govt :
"Chloramphenicol enters the foetal circulation, and if given to the mother shortly before parturition, may cause the gray baby syndrome, with cyanosis and hypothermia, owing to the limited glucoronidating capacity of the newborn infant's liver. Chloramphenicol treatment should, therefore, be avoided during the last week before parturition and during breast feeding."
