A Beautiful Mess is a genius DIY blog by Elsie and Emma, and about five months ago, the ladies launched the photo editing iPhone/iPad app by the same name. For $0.99, you get fun filters, delightful doodles, fabulous fonts, and beautiful borders. (I've been reading A LOT of children's board books lately.)
The app is very easy to navigate, and you can buy even more doodads, but the ladies seem to provide new free options with updates too. I have been happily using the app for the last five months to create Will's monthly update pics. The last two months' pics are below.
The only issue that I ran into was printing the pictures. If you print pictures that have been saved to your camera roll from the app, you just need to be aware that they are square like instagram pics, but other than that, everything is easy peasy... and here are some other fun pics because oh-my how fun is it to add colors and words to pictures.
Also, when taking Will's monthly pictures (or really any pictures of Will), I always just point and frame the camera on my phone and then start snapping (clicking? tapping?) away while smiling and acting crazy to get him to smile. I sneeze, say, "Baa Ram Ewe" in my best sheep voice, or shout, "Booshie!" Which is why I sometimes get priceless pictures like this...
