Here's my tip of the day: Take lots of photos. Lot and lots and lots of photos. Of the same thing. And take them as fast as you can.
Because sometimes you have to take a lot of photos to get just one good one (and even that one is sometimes not perfect. sigh). And most kids don't willingly stand around forever, happy to pose for you, so take those photos fast. And sometimes eyes are shut, and nostrils are flared, and eyebrows do weird things and end up looking mischievously evil, and sometimes ... occasionally, siblings look like they're choking one another. So take lots of photos. C'mon, your camera is digital. It doesn't cost anything to delete bad photos. Experiment. Change the angle from which you take your photo. Move around your kiddos til you find the vantage place where the sun doesn't cast ugly shadows on their faces. TAKE LOTS OF PHOTOS.
