advice on telling ds1 i'm pregnant, and also on parenting two

[mamaLHK]

My ds1 will be 7 years old next week. He's been my only for all this time. I thought for a long time that I wanted to keep things that way, but somewhere along the line part of me started wanting a larger family, in large part for him, but for dh and me as well. It was not clear cut, though, because I loved giving ds all of my mothering love and attention, among other reasons I had for wanting to keep things the way they were. Now I am 16 weeks pregnant. Honestly, I am somewhat nervous, although I know we thought and thought and thought about it, and made the decision to go for it. By the way, we know lots of other onlies and all the boys always ask for another sibling. My son never does. Anyway, I wanted to wait to have an amnio (I'm 45) to tell my son that I am pregnant, and that was yesterday. So ... it's time! This may be a stupid question, but any advice on how to tell such an old child, who may not be very excited? My second question is ... can anyone sum up their favorite few ideas about raising two children harmoniously? I know people have recommended the book "Siblings Without Rivalry", and I will get it when I have time, but can anyone give me a quick summary of their favorite parts? What about other recommended books and summaries? Thanks so much!!

My ds1 was 7y7m8d old when his baby bro was born. He never asked for a sibling, but when I told him I was pg, he was excited right away.

For me, it was very easy to raise them together. There was no rivalry bc my ds1 was mature enough to chalk up the slight annoyances to ds2 being a baby. They got along marvelously until just recently, but a big part of that is that ds1 is a teenager now and ds2...well, he's just a total PITA! haha
