plan ahead
Everything goes a little easier when you have a plan. Plan to take your pictures a week or two before school starts. Heck, even a week or two after. Its ok we wont tell :) This will give you time to think through your outfit choices, locations, and props.
choose a background
Lets kick the boring first day of school pic in front of the front door down!!! Figurativily not literally:) Lets face it, you know you dont have time to clean it up:) Take advantage of what is at your fingertips and head outside. Mother nature can provide some of the best backdrops.
Posing
Run, skip, jump. Dont think of posing as a static thing, Keep your eye on their every move and you may see them do something you'd like them to do again as a foundation for a pose.
Props
Props can sometimes make or break a picture so think simple and clean. A couple of vintage books or a fun cute lunch box can make for a cute picture.
