>> if you're a parent, you try hard to capture every moment of your children's lives with your camera. but because she was always taking the pictures , one mom blogger says she realized she wasn't in most of her kids' pictures and that's when she started posting.
>> reporter: like many parents with young children, allison tate, a mother of four, was everywhere in their lives, but nowhere in their pictures .
>> i'm not standing in front of the waterfalls with my 8-year-old. i knew i was not in pictures with my kids. i avoid the camera. i know i avoid the camera.
>> reporter: recently at a family party , she had every intention of remaining behind the sceneses.
>> i was kind of a mess. my 5-year-old boy said mommy, come be in the photo booth with me. i'm thinking how does my chin look? do i need to move this way?

>> i want them to see the way i looked at them, see how much i love them. i'm not perfect to look at and i am not perfect to love but i am perfectly their mother.
>> reporter: bringing their life into focus in pictures with her kids.
>> very interesting. there was a time -- i mean, i'm a kid of the '70s -- when the whole family would gather and take that family picture and you don't do that anymore. for this mom, obviously, she wanted to avoid the camera. but i love that she's opened her heart and really sparked a conversation.
>> nobody ever uses that little timer thing anymore.
>> and dad's not in it. dad's arm is in it but nothing else.
>> half the face.
>> i like that story a lot.
>>> there's a lot more to
