The piece is very interesting too. It's such a complex subject - yes it makes the 24 week abortion limit look outrageous, but with these very early babies they put so much time and effort into keeping them going and then a very high proportion will die anyway
I was interested to read that they thought the hormones the mother produced due to stress helped the baby survive. I was told that about DS (27 weeks) that the stress produces hormones which helps prepare the baby for an early birth. He doesn't (yet) show any significant problems due to his prematurity..
