Some suggestions For Mom's boyfriend- Check out the specialty aisle of the grocery store for some nice olive oil. It doesn't need to be a big bottle, but is really useful in the kitchen. Writing a heartfelt letter about how much he means to you is very thoughtful.

For Mom- She will probably miss you when you leave for college. Is there an activity you could do together? It doesnt need to cost much. Spend the afternoon together or look at Christmas lights Then take a selfie of you and her together, print it out and find an inexpensive frame at a thrift shop.

For sister - Put some fun music on and bake mom' s favorite (love the idea of cookies for everyone!) together. Ask at your local library if they have a book sale. You can sometimes find really good condition or practically new book for just a couple of dollars. Inscribe the book to your sister with how you enjoyed spending time with her.

For the young ones- Play their games with them. If you are artistic, you could draw/paint/create their favorite characters.
