Meanwhile, Reynolds will be preparing for a few more sleepless nights after grumbling about his daughter James's ability to stay up all night.
"Our baby, in particular, is, we think, allergic to sleep," he joked last March.
But he wouldn't have it any other way.
The youngest of four boys, the actor told People in February, "Having a daughter was a dream come true for me. I never admitted it out loud, to myself or my wife, but I really wanted a little girl."
It is not known whether the couple is expecting a baby boy or girl.
