I almost didn't watch it but so glad I did! My first clue was when they were discussing the risks and the dad says, *edit-rewatched, not what he said* I thought, why the heck would they do that, that's so archaic, why wouldn't they do a C-section? Still, I didn't catch on until the firefighter said, "I don't, it was the weirdest thing..." I have to say I got attached to all the characters right away. Went right to DD's room and told her she HAD to watch it.
For the poster who said it was unrealistic for multiples, I have twins, DH's father is a twin, his brother has twins, I have three friends who have twins and one who has triplets. Of those only one was ever on bed rest (not the triplet mom) and half were natural child birth. Having multiples does not always mean high risk, bed rest and C-section.
