Move over, Michelle and Bob Duggar, thereâ€™s a new baby boom in town. A California mom has just given birth to baby number 19. The UK website Parentdish reports that Christi Cason, of Lake Elsinore, California, has 19 children and has literally been pregnant for the last 13 years. We had no idea this was even medically possible, but the happy couple welcomed their tenth son, Vaughn, at the Rancho Springs Medical Center recently, and they say they might not be done. At the age of 42, Christiâ€™s body has no doubt been through the wringer. Her husband Dave, a telecom engineer, said from the hospital, â€śAlthough I've been at Christi's side for 16 births I'm still blown away at welcoming new life into the world.â€ť The couple have had 16 other children together, ranging in age from 2 to 23 years, and two additional siblings from Christiâ€™s previous relationship. The happy couple are even grandparents; their oldest daughter welcomed a son in February. Christi told the website the Lake Elsinore Patch that sheâ€™s able to manage their huge household just fine on a tight budget. â€śWe do lots of fun things together as a family,â€ť she says, â€ślike driving into the mountains singing songs on the way, or going to the beach. Even though we can't afford vacations, with a big family there are always so many other things you can do to have fun.â€ť The obviously very fertile Christi told Parentdish that she and Dave â€śhavenâ€™t ruled outâ€ť trying to conceive again. She said, "I'd still like twins â€” it would be great to experience. I think I've still got time for three more. Twenty kids would be an amazing achievement! I can't imagine a time when I stop changing nappies."
