I watched my sons daughter 11 hours a day from 1 month old until they moved away when she was 14 months. My wife was still working and I was retired so I had no problem with it. We went to see them for a week each june. After about 4 years of this we went there and from the back seat she said a particular word over and over. I asked him why she was saying this and he said he didn't know but she just started doing it. I had just changed my wifi password to that word. I know it's not really on the topic but I just wanted to relate a very strange coincidence.
