Dora Ottomas is the mother of Peter Ottomas. She lives with her son's family, which includes her three grandchildren; David, Sharla, and TommyOttomas. Her daughter-in-law, Samantha Ottomas, is pregnant with twins at the start of the game.
Strangely, Peter has no father in his family tree, which simply shows Dora as his mother. This has led some players to believe that he was adopted or born out-of-wedlock.
Dora has the lifetime want to "Have 6 Grandchildren" When the game starts, she already has three - David, Sharla and Tommy - and she will not die of old age before Samantha's twins are born, however, since there is a bug in game, Peter will not be the actual father, and Dora will not be the grandmother of the twins. This will be fixed if the game is patched. Unfortunately for Dora, the birth of the twins brings the household up to its maximum capacity of eight Sims, and without sending David to University, or the use of cheats or the Elixir of Life, Dora will usually die of old age before David is old enough to move out and free up space in the household for a sixth child.
