The most important aspect of preparing with children in mind is timing.
Pick a good time of day for your children. Mornings for 5 and under are usually best, late evenings are not recommended and of course fed & napped this goes for daddy too!
Solid colors for clothing this keeps the attention on the subject’s faces & expressions.
If coordinating a group like colors are best, solids, earth tones, black, white is classic especially for children.
Bringing special props, family car, teddy bear, rocking chairs, pets ect. Bring memories & meaning to your portrait
