Your agency will need to build a small portfolio of photos to show clients. Depending on who you talk to they will recommend you either take decent photographs your self or to have a professional photographer take some shots. There are benefits to either way, but if you are just starting we lean towards taking them yourself, particularly for infants. They change so fast and mostly you just need to show their cute little personality and have some good lighting. If your child is a little older and you’ve decided to get more serious it may make sense to get some professional photographs taken from someone who specialized in baby and child modeling since they know the industry. The photos do not need to be glamorous or overly posed, just get some that show their personality – head shots and body shots.
