Opinions on how to honor the new Grandmothers and Aunt at my baby shower?

My baby shower is just over two months away, and with summer coming up, (vacations, reunions, etc) we're trying to get everything planned out now so we won't have to in the rush of other things happening. My mother and sister are hosting it, and I want to get something special to give them at the end of the shower as a sort of, thank you, and I intend on doing the same for my soon-to-be mother in law, as she will be there as well. this will be my mother's second grandchild, my sister's first nephew, and my fiance's mother's first grandchild, and as a gift i was thinking of getting them something on the lines of a brag book and a personal something, such as a "nana" or "aunt" gift (such as the ones that hallmark have). Here's where i run into my dilemma...my fiance's mother is just now trying to be a part of his life constantly (and no, it's not because of our son). She was sort of a "come and go" mother as i call them, so his grandmother raised him the majority of his life, and she will be at the shower too. beings the situation, I can't honor his mother at the shower and not his grandmother, and I can't honor his grandmother, and not my own. So that makes me buying for five people, instead of the three i originally started out with, which isn't a problem, but it just cuts my gift price range a little bit. So, my question is, what would be a good gift that i could give them all (not necessarily the same, but similar) that would fall with in a 10-15 dollar price range? I want it to be personal as this is a big event for them, not only myself. Thanks for you help!
