How do I best preserve my family's identity and still keep my readers interested

[bohomeanrhapsody]

Hi guys!  I am struggling between really wanting to show pictures of my sweet kids, and wanting to conceal their identity.

I really would like to show just a few pictures of my children in the beginning, just to provide my readers a little window into our lives (I have some great ones).  In the beginning I will not be listing my location, but in the future I would like to do use my blog to connect with the community and do some charity work - and would like to list my location down the road. 

Here are my thoughts.  Can I show just a few pictures now, change my children's names - and after I get a following (hopefully I get a following), I can delete the past posted pictures when I add a location?

Does that seem safe to you?  Thanks!
