Does the father of the bride give a gift to the mother of the bride? What did you do?

i have never heard of such a thing, and i dont think it is necessary
for one, this is Kaitlins day, not her moms

secondly...this day will be expensive enough as it is (just kidding of course)

now
having said all this, this may be somewhat of a bittersweet day for her mom (especially if Kaitlin still lives with you guys and wont move out until she gets married)

i dont know how much your wife sees her identity wrapped up in "being the mother" but if this day will turn her into an empty nester, that may have a negative effect on her

so my suggestion would be to save the special gifts for a week or so after she gets married
maybe take your wife on a second honeymoon, or just a long weekend
