I missed many months of DS1's life too, and for that I'll always be sad, but I can tell you it was totally worth it and Im glad I had them fairly close together. Watching DS1 and 2 together and the bond they have is so beautful. Everytime DS1 says his brother is his best friend it just melts my heart. Yes I missed out on some of DS1's 2nd year, but the gift I gave him was amazing. This is why I was willing to put myself through hell to do it again (though it hasnt got to that yet).
