I'm so glad to hear all of the positive news!
My DD's PDA was closed with 3 days of ibuprofen, so I'm hoping your son has a similar result. Has he started feeds and is he tolerating them?
Don't be disappointed if the attempt off CPAP is short lived, they push these little babies quite hard and as a result it often ends up as only a short attempt. Have they discussed 'cycling' him or are they planning on taking him off all together?
I tried to PM you but it wouldn't let me (not sure if anyone knows why - is it because of how new the profile is?), please feel free to PM me if you'd like to discuss anything! I can also send you some pictures of my DD's NICU journey and how she is looking now if that is of any assistance to you.
I hope your wife gets a cuddle soon, it was a real turning point for me, emotionally. It made me feel like a real mum :-)
