18 was not enough for the Duggars. They are welcoming their 19th child. "We are so thrilled," says Michelle, 42. "We just couldn’t believe it is happening." Jim Bob, 44, agrees: "This never gets old. We are so grateful for each child. We are looking forward to our first grand baby and our 19th child." Oldest son Joshua, 21 and his wife Anna, 21, are expecting daughter Mackynzie Renée next month, so she will be older than her new aunt or uncle. Congrats to the happy family!
