Wow, 25 weeks. It shocks me to hear about bubbas born under 30 weeks. DD was delivered at (planned c/s) 34+1 but measured at 30-31w because of IUGR.
I've seen pictures of under 28w they look so fragile, I'd be too scared to even think about touching one.
DD was 3lb 12oz but I was never scared of her. She looked fully formed although my dad thought that her eyes looked "spooky" as the eyelids were, not see-through, but just looked prem.
When some of my family came to visit in RCH when DD was 3 1/2 weeks old she was about 4lb something. Still very much under 2kg anyway. And DP and I were so comfortable with changing her nappy and passing her around and family was too scared to touch her.
Mind you, she still had a long-line (a drip thingy) in her arm and quite a few wires monitoring her.
