Just to continue the lark about big, big babies. . .
According to the interwebs, a 16 lb baby boy was born via c-section in Texas. His mother suffered from GD. The doctor's expected him to weigh 12-13 lbs, instead he was 16, and 24 inches long. :) He's cute, too. :D
According to that same article: According to Guinness World Records, the biggest baby on record weighed in at 23.12 pounds at birth back in 1879 in Canada. I don't know what the situation of obstetric/midwifery care was in Canada in 1879.
In looking up the record online, I found: Anna Bates (née Swan) (Canada) (1846-88), who measured 2.27 m (7 ft 5.5 in) tall, gave birth to a boy weighing 10.8 kg (23 lb 12 oz) and measuring 76 cm (30 in) long, at her home in Seville, Ohio, USA, on January 19, 1879, but the baby died 11 hours later. (Both his mother and father had giantism and worked for PT Barnum). It doesn't say whether or not that homebirth was attended, nor does it give the cause of death.
Fascinating, though. There are other births, too, where apparently large infants survived -- infants that were 20 or so lbs at birth -- born in italy and the UK. both apparently under midwifery care, and both before 1955!
Interesting reading, really.
