Multiple births, multiple happiness

Ever since my eldest son announced he was expecting identical twins, I've been fascinated with doublets, triplets, quadruplets etc. Here's a story about a very rare happening: identical quads. I imagine these parent won't be sleeping for the next couple of years!
Early this morning my son called me to say they had had a "close call." Leo had rushed Shannon to the hospital with contractions in the middle of the night. Nurses announced she was dilating, but since she's not at 35 weeks -- the minimum her ob/gyn wants her to go -- the nurses gave her a shot. All is well so far, but as my son was driving to work, he told me was exhausted and sleepy.
The true sign of parenthood.
