Is it forbidden to address one's wife as "Baba"?

It has been previously clarified that it is disliked for a man to call his wife by a term that refers to a woman forbidden to him [for marriage]. As for his calling his wife by the term "baba" (daddy), there is nothing reported concerning it, and it appears there is no difference between it and his calling her "mama" (mommy). However, it is preferable to avoid this type of appellation.
