Michigan couple Kateri and Jay Schwandt are the parents of 13 children, all boys, ranging in ages from 25 to two years old. With Kateri pregnant once again, they are keeping with the family tradition of waiting until the birth to find out the sex of the baby. As they prepare for their new arrival, chaos ensues as only it can when you have 13 boys, all at different stages in their lives, to watch over and be there for. With all that is going on around them, Kateri and Jay are making sure to do their best to relish each and every moment of this pregnancy, as it may be their last. But a big question remains, will number 14 be another son…or their first daughter?
