I feel so bad :( My OB, the one who brought my LO into this world safely and helped through all the complications, made the uncomfortable visits prior to labor bearable, and who even came in on her day off to see baby and I before we got discharged from the hospital...she ended up losing her eldest daughter. Don't know how, but her eldest daughter died and I just feel horrible and I want to do something for her but I don't know what...I can't imagine the pain she's going through :(
