Feeling so Sad

I just got home from a really great weekend with the nieces.. I'll post about it in a moment but I needed to unload something first.. A friend of mine on a board that I frequent had her twin baby girls too early. She was due in December and the girls arrived in October at 29 weeks. They knew that one of the girls had a heart problem which got fixed through surgery but unfortunately her lungs weren't doing all that great and unfortunately they had to make a decision that was for the best. Baby Brooklyn died on Friday night.. I am so sad for my friend and even though I've been through death issues before with many family members I don't think I've ever personally known anyone who lost a baby so young. I don't know what to do or say for my friend. I was planning on getting her something for the girls off their registry and sending it to them in celebration of the births once they were home. Now I don't know what to do. The other baby is doing fantastic by the way and doing great for being born at 29 weeks. I just am at a loss though for my friend. Sorry if this post sounds rather rambly...
