Stop - it's not that deep! Consider this: it's your photographer's job to make your family look great and to deliver photos you'll be excited to show off, not yours. That means I'll handle getting the kids to smile for the camera, but also I'll catch fun moments that aren't posed or planned. You might even enjoy the experience - simply hanging with your (unusually well-dressed) family in a picturesque spot!
This family shoot was a great example. The parents had a couple things in mind they wanted to capture, but the kids enjoyed suggesting poses and things they wanted to do, too! Awesome! We went with it and got such a variety of sweet family moments. And definitely no tears or tantrums ;)
