The other day I had to apologize to all of my boys about my having dropped them or let them fall of the bed/couch/counter, etc. (several times each).
Why did I feel the need to apologize, you ask? They couldn't possibly remember (most likely due to the repeated head trauma).
Because I failed to destroy the evidence.
When my boys were babies, I started a journal for each one. I never did baby books for them, and I knew I wouldn't remember the cute things they said and did.
Apparently, I didn't remember the times I dropped them, either.
When we came upon the books recently, each child started reading their respective journals, thereby learning the truth about what a negligent mother I was.
I still think they turned out ok!
