Some baby sisters get strangled and you have to set the camera down so you can rescue her.
Some shots don't work for the product, but the look on your three year olds face perfectly displays the joys of being three.
Sometimes the stuffed dog appears as soon as you snap the shot.
Sometimes the camera catches how you see them. A little boy.
Absorbed in his book.
Sometimes the camera makes them look older than three and you want to reach out and kiss and snuggle them because you can't believe how fast they are growing up.
