Each season got its own colored folder with similarly colored construction paper inside. There are photos in the folder associated with each season. When she shows interest, we talk about the photos and that season and I give her the option to paste the photos on the paper. Once the photos are pasted, I'll 3-hole punch them and put them in the folder as a booklet for her to keep.
You can always look your own photos up for each season like I did, but I thought I'd show you what I used to help get you thinking about what photos you might want to use.
