It's like newborn shoots. It all seems perfect, but there are usually breaks for feeding, soothing, getting back to sleep, before we can continue. Some babies just can't settle. I have seen it all.
The digital world has made a photographers life somewhat easier, in that we can take more photos to get "the good one" unlike when I started out 20 years ago when we just had a couple of rolls of 36 or 24 film. But our expectations are also raised, as we CAN take more photos to get the good one.
Kids only have a small amount of patience. Even the super smiley, "always happy" babies. They have a breaking point, and in front of a camera it is easy to see when it is time to stop.
Some kids are just shy from the beginning, so the photographer needs the freedom to get contact with that child so that they feel safe and enjoy the experience of being photographed.
These three kids, 3 year old twin brother and sister, and 10 month old baby sister, were just adorable. They were very shy, the boy didn't like balloons touching the floor, but luckily bubbles saved the day! I include an "in-between" shot, a truth, and a reality from this shoot, just to show that kids aren't perfect, even though it might look like that from the outside. I think it's important to show.
