I have a 4 year old and I post a lot of pictures of my kid, but like privately. I use an app called tinybeans. You have to be explicitly invited. Grandma gets emails because she can't use apps. everyone is happy. My kid's pictures are hidden away from facebook and family members have to take much more active action to share her photos beyond themselves. And they know that means excommunication from the picture firehose, so they don't. That's how I've managed this. I mean... there's still a bunch of embarrassing stuff in there, but at least the only people who can see it are the people who were traditionally privy to embarrassing kid shit anyway.
