DS is 17 and was a result of many years trying and finally through third round of IVF. He's never been upset about being an only child before and has never minded but he went to stay with his girlfriend's family about 2 weeks ago (she has 3 siblings) and has come back continually saying how great it was and how he wishes he had siblings now. He knows the stuggle we went through and understands why we didnt try again after he was born, and I know he doesn't want to make me feel guilty but I feel so upset that I couldn't give him what he should have had. Don't really know why I'm posting, just have been feeling very down about it recently
