If you thought the Duggar family couldn't get any bigger, think again: According to PEOPLE, Josh and Anna Duggar welcomed their second child Wednesday - a baby boy, weighing 8 lbs., 5 oz.

The couple, aged 23 and 22, respectively, did not release the name of their son, though they did say that it stars with the letter M.

This is the couple's second child. They also have a 20-month old daughter, MacKynzie.

Josh is the son of Jim Bob and Michelle Duggar, the stars of TLC's '19 Kids and Counting.'
