DES MOINES, Iowa (Reuters) - The biggest of the world`s only septuplets was the first to eat on Saturday and a hospital official said a report expected to say whether any of them were identical was delayed. Kenneth Robert McCaughey, also the first of the four brothers and three sisters to breathe without mechanical help, took food other than intravenous fluids for the first time since their birth on Wednesday. Hospital officials said Kenneth remained in fair condition while his smaller siblings, although still in serious condition and breathing with ventilator assistance, had also improved. The pathology report - expected to show whether any of the seven were identical - had been expected on Friday. But Iowa Methodist senior vice president Sharon Simmons told Reuters that it might not be completed for another week to 10 days. The septuplets slept soundly on Friday night and spent a largely uneventful day on Saturday except for Kenneth`s meal. Mother Bobbi McCaughey, 29, was in good condition late Saturday. No discharge date for her was set, officials said. She has planned to be home for Thanksgiving, though the babies were expected to remain in the hospital into January. In the McCaughey`s hometown of Carlisle, seven miles outside Des Moines, the American Red Cross on Saturday held babysitting lessons for about a dozen local 10 to 14-year-olds, some of whom said they hoped some day to babysit the seven. Neighbours at a local church raised $1,500 for Bobbi and father Kenny McCaughey on Saturday by selling candybars packaged in special wrappers with the babies` names on them. Carlisle will honor the septuplets at its annual Christmas tree-lighting ceremony on Sunday, town officials said. Baby Kenneth was nicknamed "Hercules" by hospital staff because he held up all the other babies in the womb. He was held for the first time on Friday by Bobbi and Kenny, 27. In the first interview granted by the mother, she told a Des Moines television station on Friday that she said she knew her decision months ago to keep all seven fetuses, rather than abort some, was "extraordinary." Mothers carrying multiple fetuses routinely undergo "selective reduction," or abortion of some, to give the others a better chance of survival. But Bobbi said her faith ruled that out, as did a question for which she had no answer. Kenny works as a clerk at a car dealership in Carlise.
