My DS2 was born at 31+3 by emCS due to placenta praevia. At that point I had had 3 MCs and DS1 12 months earlier.
He was in hospital for 5 weeks and came home weighing 5 lbs.
He is now almost 6 yrs and looks like he could become a prop forward for any rugby team who'd have him !
It is horrible to see your LO being prodded and poked in NICU and I count myself v lucky that we had a v healthy outcome.
I never BF DS2 but expressed for a little while, so he was mixfed fed for the first 3 or 4 months. I still have an occasional guilty twinge about that as both his siblings got a lot more breast milk - but at least he got just as many cuddles...
DS2 also had reflux, used to be on all sort of meds, and had a barium swallow when he was almost 6 months (biological) age. Reflux and vomiting stopped really suddenly once solids were introduced when he was about 7 months old (I waited a bit longer because of his prematurity).
How old is your DS now? Age and corrected age? How long has he been home now after his readmission?
I understand your frustration about going out and personally, I would and I did as I also had a toddler to entertain at the time. Being exposed to bugs and germs is what builds baby's immune systems. It is a shame you had the added worry of RSV/bronchiolitis/ARDS - how scary!
Can you keep him close to you when out and about ie in a sling? Make sure you wash your hands after having been out and get others who want to hold him to wash their hands as well.
FWIW, I found the first 2 winters with DS2 really hard (he was a March baby) - he caught lots of coughs and colds, including croup and (still) tends to be a bit wheeze when he has a cold.
On the other hand, he is fit and well and confident and has enjoyed starting school last year.
It is hard to see when you have such a tiny helpless fragile baby to look after, but even premature babies grow up and get bigger and stronger. In the meantime, I think for your own sanity and your childs longterm confindence it is so important to try not to worry TOO much and offer them as normal a life as possible.
Oh gawd, you are bringing back memories...
