For bridal showers, baby showers, birthday parties, etc. Have the Maid of Honor write the gift giver's name on a label and stick it on the box right after it's opened. Like this idea so they are not writing non-stop and they can enjoy!
I love you dad, I have had the best dad in the world and my baby will have the best Grandpa in the world. I always wanted my daughter to have the relationship with her dad that I have with you. You're my hero dad.
