DS (now 10mo) was born at 26wks exactly and this is how is was for us;
5lb 5oz, Apgar good, after 2 hrs with me he was taken down to NICU for antibiotics and had a cannula fitted. Heel pricks taken every 3 hours for 4 days - jaundiced so on a lightbed most of the time, blood sugar levels up and down, antibiotics twice daily.
He had tongue tie and couldn't latch on, so was given formula to keep his weight up. I tried to hand express colostrum, it was hard going. After a rough first night on the ward, I paid approx £75 per night to have a side room, it helped while I was trying to establish bf. Eventually let us go home after 4 days in Hosp.
Tongue tie divided at home by specialist at 1wk old. Second tongue tie (posterior) divided at 2 months old!
We had an awful time feeding for the first 4 months, since then it's been easy and pain free, so for me it was worth persevering. If you're keen to bf, I highly recommend finding out where your nearest bf advice clinics are, and their opening hours - I went to three different local ones, all had different approaches, one was brilliant, one was absolutely awful!
I was told that 36wks is a particularly tricky age for starting bfing, apparently earlier babies do better, and later babies do better.
DS had reflux which settled after he weaned at 7 months. Only got better around 6mo after a few different meds had been tried, then we stopped giving him any meds for it at 8.5 mo, as weaning seemed to cure it.
He was def not ready for weaning until 7mo, even tho I did try earlier as all his contemporaries started weaning at about 5mo.
Main thing I'd say is don't let the HVs panic you about DCs weight - we ended up weighing DS daily in a colander on the kitchen scales, and got really stressed about his weight. Completely over the top pressure from the communtity midwives and HVs to get vast quantities of formula into his tiny tummy, he just couldn't do it.
Due to the reflux and me wanting to keep him close, he practically lived in a sling for the first few months. I used a BabaSling, which was good when he was tiny not so great now he's such a big lump
Sorry this is such a long post! Good luck with your cs!
