Nostalgic Reading

Do any of you ever have those few books that made you fall in love with reading? You just can't quite let go of them because what if you want to read them again? I know I have some that are like this. I have at least one babysitter's club books, a few dr. Seuss books and some that I had purchased at school book fairs. Lucky thing is too that I held onto my Dr. Seuss books because my children are in the early stages of learning to read. I am hoping that they pick up my love for reading but so far it does not look like they will. That might change when they get a little older but for now, I'll just settle for teaching them the wonders of reading and let them decide on it.
What are some of your favorite nostalgic books that you have held onto? Let me know down in the comments
