Sounds perfect to me. Let her talk to you about her feelings regarding disappointment or not. It took me a few months to be able to speak to anyone about it, and the last thing I wanted to look like was an ingrate by talking to someone about it when I had a perfectly healthy baby girl in my arms....It is a very mixed emotion, and still is for me, as mine was a true emergency c/s and am very very lucky Charlotte was perfect. But despite knowing it HAD to be done, it doesn't seem to take away from the fact that it isn't what I wanted.

As you say, she may be perfectly fine with it, but if she isn't let her come to you. And congrats to your friend!
