From a mom's point a view as well as someone who reviews hundreds of blogs weekly, here is my advice:
Yes, add pics & names! BUT... do some creative photography, photo editing and change the names to protect the innocent!. Make these changes to where you feel comfortable.
A visual and reference of your life/fam is so important for the tone of your blog as well as readership so don't shy away from the reveal but get creative with it. For example only post side or back shots, maybe just show the activity but not the actual child or get creative and blur/stripe out just enough to conceal your identity. I've seen many blogs where they place a black, tape-like stripe over everyone's eyes. If done well, it's kind of a fun and catchy effect. Same with names. Use a first initial or nickname. As long as you are constant, people will catch on.
I think this question is something we all really struggle with. How much do we want to put ourselves our our family's out there?!?
