I'm a parent. My daughter is 11 and she's already quite happily speaking her own thoughts about things and as soon as we have a mutual good hair day, we're sending a picture to the shrine of the two of us. I personally think if the parents wish to submit the picture of their kids, or say the 'kid' (if old enough to listen, understand and send a digital image to FTL) does, then it shouldn't be an issue.
I'm having fun raising my own kid, don't personally want to be responisble for raising someone else's.
