While Kenzy was born 4 lbs., 15 oz., Kenzley was born 5 lbs., 9 oz. "So far Kenzy is our milk guzzler," and Kenzley is enjoying "taking her place as the youngest and baby of our tribe" and absolutely "loves to be held," the proud mama shared. The Alarcons are also parents to Brittney, 17, Sarah, 13, Hunter, 10, twins Zachary and Zoey, 6, and twins Oliver and Olivia, 4, according to Good Morning America.
