Thinking of them both, it is a frightening time and they will need all your support.
If it helps at all my LO was 26+3 weeks and is now home, the only hangover she has from our experience is reflux and bad wind, plus the odd choking on her feed. Even though when born these babies are tiny and vulnerable, they are incredible fighters and are really strong. It amazes me how physically strong Emily is sometimes.
Please keep us updated on your friends LO. Please take comfort in the fact that the technology and care that is available today for these small babies is amazing and that is why so many go onto to be big strong babies/toddlers then adults.
Big hugs...xx
