From the first episode I suspected that the baby was still alive, for 2 simple reasons. You never heard/saw that the children was killed and she only started 1 year after the incident to get back into shape. But I know when her boss said "I know Sam, I know".
I liked the series, would have loved more, but I am also kind of glad that they did not end it in a huge cliffhanger. It was definitely one of my favorite shows this year.
