Hey FLTC, now that's interesting that she asked about separate or singular gifts. If you think of pursuit then jumping on the singular gift idea would not be a good action. But she offered this up first which could be a very small sign.
So thinking out loud here, maybe you tell your wife you had been contemplating a gift for your daughter already. Be sure to have some solid ideas to back this up. Then say that a gift from the two of you would be a nice gesture to your daughter to show the you both are proud of her and love her. But you would like to get a gift just from you as well because of the special bond between fathers and daughters.
