Baby shower host gifts...help!

Emma
So my shower is next Sunday and I really want to get my hosts a little something as a thank you. It's 4 of my cousins, and they're superrrrrr picky! 2 of them are all organic everything(bath products, food, makeup, like literally everything), 2 of them are gluten free while the other 2 are low carb. They're all Starbucks lovers so my original plan was to get them gift cards, but now the one is pregnant and I'm not sure if she's still drinking coffee or not....what about like Starbucks tumblers? I don't know!!
Maybe I'm thinking too much into it? Anyone have any ideas for gifts for super picky people that are relatively inexpensive?(especially since I need to get 4 of them)
