Is it normal for single parent families to have less pictures?
I am in my early 20s and was looking through my family photo album. My dad left me and my mom when I was three years old. There are tons of pictures of me, me and family pets, me and other family members and even a few of me and my mom. From grade one until present day, all there is are school pictures from every grade, pictures of just me on my birthday and Christmas (these stop by junior high) and less than five of me and my mom and none of me with family pets or other family members.
Mom says this is because she was a single parent and low on finances so she either didn't have time to take pictures or couldn't afford to pay a photographer but I am worrying the lack of photos will be depressing as I get older and forget my past but, unlike others, can't look back on pictures for memories.
Is the lack of pictures normal and is my worrying normal?
