oh and one more thing if anyone can help? can i put the pictures up for critique without asking the parents? I never see the parents to ask them if this is ok as my neighbour drops the kids off.. I guess I could ask my neighbour to ask her for me but I wouldnt want to put her in that position... to me it seems like an uncomfortable question... like, "hey thanks for letting me take pictures of your baby.. can I put them online!"
I am not sure what the laws are in Scotland, but in Canada, where I live, these children would be considered minors and you should probably have their parents permssion to both photograph them (I notice that you have this) and place them on the web. In some countries, unless it is a public figure, e.g., politician, film star, singer, etc., you cannot post a picture of anyone on the web without their permission, or that of their legal guardian. This permission is often obtained in the form of a "model release", even if they are not technically models, it is simply a signed consent form giving you the right to "publish" their images. You should note also that even though you hold the copyright to these images, this copyright does not technically give you the "right" to post their pictures on the web. You can find "model release" forms on the web by searching with Google. You might want engage a lawyer, or buy a half hour of his/her time to make sure you know what the laws/rules are in Scotland. and that any "consent form" you might develop is bullet-proof. (Afterthought - you might also look for a "portrait" release form. If such a thing exists, it is probably similar to a model release form.)
I know this sounds like I am overcomplicating things, and maybe I am, but put yourselves in the parent's shoes, suppose you opened up a web-site and saw, what were effectively unauthorized images of your small children taken by someone that you may or may not know...it doesn't even have to be the parents, it could be an acquaintance or a relative...e.g., Aunt Mary phones up one day and says, "Hayley...your nephew, Freddy, found pics of your new baby on the web...I didn't realize that was being done...you didn't tell me..." I know your images and intent are just nice "baby picture" type images, but there are just too many "perverts" out there who "troll" the web looking for pics of young kids. I for one, would not want someone else taking pictures of my kids, when they were much younger, and posting them on the web for the world to see, particularly without my knowing about it. Heck, I don't even like it when my wife posts pics of us and/or me doing something on her Facebook page. (and yes, I do tend to be a bit of a cynic about things like this...but that is just me)
Regardless, I think it is something you need to deal with and the sooner the better. HTH.
