Viability After 30 weeks

I'm probably posting something that's already been posted,
but I was just wondering after 30 weeks, when is the earliest they will let you go home with your baby if you deliver?
When will they have minimal complications?
I know its a really good chance of survival, but does that depend on the sex too? (I've heard girls are stronger)

I'm kind of coming in here a bit early, but I figured this would be a better place to ask (:

From what I read/was told - 34 weeks is the real viability when you might avoid big problems with breathing, by 34 weeks babies should be able to breath on their own. At 35 weeks, they might be able to feed on their own as well. It also depends on how fast they are gaining weight, how stable their body temperature is etc. 36 weekers are considered almost full term and most likely won't need any help at all.

babies born after 37 weeks are not considered premature so i think that is the earliest they can come home with you. It would depend on the apgar score and how well bubs is feeding etc.

I dont know about the viability at each week but several women have had healthy babies on here at 33 weeks. And i know from reading that at 35 weeks 99% of babies born will survive and have minimal problems.

Hi. 30wks is actually a good gestation - not ideal, but 95-98% survive at 28wks with the majority not requiring ventilation. The main issues are maintaining body heat and feeding.

Full lung maturity isn't reached until 34wks, but this isn't something which happens overnight, it is a gradual process. The lungs begin to produce something called surfactant from 24wks. This is an oily substance which allows the lungs to reinflate after we exhale. Without it, babies can't breath for themselves. Everyday in the womb a baby produces more and more until at 34wks they are able to breath adequately without any assitance.

Usually from 28wks there is enough surfactant to enable babies to survive with minimal intervention - maybe a few weeks on CPAP, or oxygen. CPAP is a blast of air which stops the lungs from fully deflating on exhaling - thus making it easier to take an inward breath again. It isn't as invasive as a ventilator (which blasts the lungs with high forces of air), and thus doesn't cause lung damage.

It isn't an exact science, because every baby is different. There are some born at 27wks who never need ventilation, and are home within weeks. When we were in intensive care with Evie, there was a baby girl born at 25wks, who was ventilated for 1 week, and home within 4wks. Conversely, there was a baby born at 28, who fought for weeks but sadly didn't make it - tho this is unusual. For the most part, 28wks is a good milestone. Aside from lungs, there is less risk of infection, brain bleeds and lung problems, and with each passing day thereafter the chances of good health increase massively.

We were told that if we could get Evie to 28/30wks we would be "home and dry". Statistically, girls do have less complications if born early, but a strong, otherwise healthy boy can also do extremely well.

There are many unknowns with prematurity, but at 24wks Evie did many things which defied the odds. She could breastfeed at 29wks, and had no additional complications. A baby like her would have been discharged within a matter of days if born after 30 wks. It isn't always the case, but I will be happy if I get these twins to 30wks. x
