Usually small children are more comfortable being photographed indoors. But usually the problem is that when taking photos indoors, the photos tend to be blurry and dark. So, you can use these settings, KEE friends...
1. Use an aperture with a small number
You can use AE mode on your camera and use a small aperture number. Apart from that, you can take a photo location close to a window so that your photo gets enough light and isn't dark. If the photo is still dark, you can increase the ISO on your camera.
If you want to photograph a child who is moving a lot, you need to be close to a light source or a bright place so that you can increase the shutter speed and your photo will not be blurry and the child's movements can be recorded well. Apart from that, with a small aperture number, you can create a bokeh effect in your photos so that the photos look professional.
