I use social media quite a lot, I've been posting pictures of DC since I started to use facebook and then instagram so when my oldest was around 4 and there's pictures of my other children from birth to now. It's nice to have them there to look back on but I do wonder sometimes whether I should, I find some of my own childhood pictures a bit embarrasing. My DC aren't too bothered by it, youngest is too young understand, middle one couldn't care less, my oldest is a teenager now so she cares a little more and I ask her permission before posting anything of her. Most people I know also post pictures of their DC regularly, I only know a couple who don't at all
