(CNN) -- A woman in California delivered what may be the nation's second live-born set of octuplets on Monday morning, surprising doctors who expected seven babies.
The first three to seven days will be critical for the infants, Dr. Mandhir Gupta said.
The six boys and two girls -- ranging in weight from 1 pound 8 ounces to 3 pounds 4 ounces -- were generally doing well in incubators following their Caesarean-section delivery at Kaiser Permanente hospital in Bellflower, California, doctors said.when she was hospitalized seven weeks ago and ordered to bed rest.
Over a seven-week period, a team of 46 physicians, nurses and other staff prepared for the births. When they started the delivery Monday -- more than nine weeks before the babies would be full term -- they were in for a surprise.
"After we got to Baby G, we were surprised by the discovery of a Baby H," Maples said.
