Hard to say really, babies born earlier can sail through and older can struggle and vice versa. If baby is a good weight he/she will generally do better(although my little girl did amazing at 1lb 8.5oz compared to babies twice her size)
Baby will be in nicu and in incubator
He/she will be on sone sort of breathing machine, usually just CPAP which is just pressure going in the nose to remind them to breathe on their own.
It's just a case of getting through each day, getting bigger and starting to get milk into them. It gradually changes as baby gets bigger and stronger. There might be some other problems that appear.
Baby should do well though, just a case of growing and establishing feeding.
