No!!!!!
#1 and # 2 are 1 day shy of 4 years apart. #2 and #3 are 19 months apart. I have the best of all worlds. My oldest acts like an oldest and an only, my middle is the only girl and only 19 months older than little DS, so she is like an oldest, youngest, middle, and only, and DS is totally the baby and everyone likes it that way LOL.
They are almost 15, almost 11, and 9 now and I look at my family and peers who are still having babies and cannot imagine going through that again. I did my years and years of baby and toddler duty and am so glad my kids are the ages they are now.
My only regret is that my oldest didn't really get to grow up with a brother, and my DD doesn't have a sister. I have 4 sisters and they are my absolute best friends in the whole world. DD will never know what that is like. No regrets at all about the youngest...he gets the cool high school teenage brother and a sister that bosses him around and keeps him on his toes.
I never wish for another child, but with only three short years before DS14 graduates high school and leaves for college, I could collapse into a puddle of tears just thinking about how fast the time has gone.
