"Ashton has always wanted three or four kids, but Mila only wants two," an insider tells Life & Style. "Now that she'll have one of each gender, Mila feels she can be done having babies."

Despite Ashton's desire for a bigger brood, he's looking forward to having a special "father-son bond" with this one.

"Even though they told everyone that they'd be happy with another girl, a son is what they were hoping for," the insider shares.
