Today, I'm sharing April and May. My albums go chronologically, so if I do any "traditional" 12x12 pages, they go in the book at the proper spot between the monthly collage-style Project Life pages. You'll see a couple of those below, and it's not really just either/or, since I sometimes use the Project Life divided pages for "regular" scrapbooking too!
April featured two Easter egg hunts and other springtime fun. Claire turned five months, so I included her belly sticker and some milestone updates, like I do every month. Kate was just learning to write her name, so I included a 6x12 showing her letter-writing and a "footprint butterfly" she watercolored.
May's highlight was our beach vacation, so that got a few pages of its own (not to mention a whole Shutterfly photobook!). May's main collage page explained how the month was pretty much divided into "preparing for the beach," "the beach," and "wishing we were still at the beach." Matt and I went to a Derby party, and I included a shot of a typical morning in our house, the girls playing on the floor of our room while we get ready.
