This is a slightly weird one, so I'm prepared to get laughed at / flamed, but here goes...
The child in the attached image (at least I hope it's attached) is "W" sitting. Now where it's very good for showing off the shoes, it's also developmentally a really bad position for kids to sit in, and one that parents / guardians should be actively discouraging kids to use, unless it's just for a really short period of time. It can indicate weakness in the hips and trunk. Am I a little silly for thinking that they shouldn't have the child in this position in their advertising??
