Toddler photography can be the most challenging photos to take. This is my daughter actually and I am learning so much by photographing her and every stage she goes through. She is 11 months old here and what I have learned by all the toddlers I have photographed is you have to let them do their thing. Children look the most beautiful when they are exploring, looking at things or laughing at you because you did something funny. A few ways to get toddlers on the move to stop for a few minutes is to give them something to do. Putting them up against a wall or in a corner helps them from escaping fast as well. Most importantly don't force a toddler to stay still, pose and smile. Not only does it not look natural, but they don't like it and then you miss capturing their spirits. Don't be afraid to let your child crawl in the dirt or eat something messy. Get down on their level, it makes them curious and they will look at you more. It makes for the best photos! When in doubt hire a professional because unless you know how to operate a camera fast and have a high end camera you won't be able to really get what you are looking for. Children grow so fast so I say spend the money and get it done right.
