Do babies see...

I Googled "do babies see" the other day and the number one auto suggestion was "do babies see color" followed by "do babies see ghosts." Is it bad that I was actually trying to Google "do babies see ghosts?" ha. Sometimes Brooklyn will look at literally nothing and just crack herself up. Makes me wonder sometimes if relatives that have passed away are making faces at her. Or she's just a baby and easily amused looking at the corner of the couch.
