my twins were 10 weeks early due to IUGR in twin 1 and less that 10% cord flow
they were delivered via section as both were breech and needed assistance straight away
they spent 33 days in NICU /special care and came home at less than 36 weeks gestation and under 2kg as they said they were feeding Ok and would fatten up quicker at home
After 28 weeks twin have a 90% chance of being OK long term- they still may need assistance with breathing etc at the start but the long term prognosis is what they look at!
Babies can't such/swallow before 34 weeks so they need to be gavage fed and have trouble maintaining their body temps before this time
Usually, after 36 weeks you are OK for them to room with you and need little or no special care but ideally it is better for them t be delivered at 37+ weeks
Good luck and if you want any questions answered please ask away
for everyday they are inside you is two days less in special care - so keep them baking
