hi there julie
congrats on the birth of your twins

my twins were born at 31 weeks at 1400g and 1800grams.
My sons apgar score was 1 and then 3 and my daughters was 3 and 5. He had a 10 chance of survival and she had a 20 %.

They were in hospital until they could feed without a gavage and maintain their body temp. They were in for 33 days and came home at 36 weeks gestation. My son weighed 1800g and my daughter 2400g
So the main thing is that they can feed and keep themselves warm. The suck swallow reflex usually starts from 34 weeks, so it is usually some time after that they can come home
good luck and if you need any advice- just yell out
btw they are now healthy 4 year olds and have had no major probs being prem
small beginnings but big futures
HTH
