Identity theft

Does anyone else find themselves when describing the baby's activities referring to the baby as "we"?
"We just ate 8 ounces" or "we just had an enormous poop".
Why do people do this? Have I given up the fact that I am an individual adult with my own life and needs to become someone who is identified only through my offspring?
Or is it just me?

I am not depressed per se, just feeling a little down.
