Instead of wide-angle
shots of baby's whole body, get close to your subject, and
use your zoom to capture his/her expressions and his/her
actions. Get someone to make him/her laugh.
Choose a background with
light, warm colour, so that your picture will look bright
and pleasing to the eye.
Don't be afraid to get
close to your subject and take lots of photos. A good photo
of someone in action makes for a wonderful portrait, and the
more photos you take, the better your chances of getting
exactly the image you want.
