I have inserts that are 4x6 and used the "1st birthday on one, the wild haired smiley face on two of the 4x6 pages and the bottom of the "one" word art on the 4th 4x6 page.
The last page has the word art and will hold a 5x7 photo. The paper dolls have pop dots behind them so that the pictures can fit behind them. The "one" word art I hand just to fit the page.
