M.F.
My daughter had really bad colic and cried when ever I left the room around this age. One day when I needed a break my husband was holding her and she was screaming at the top of her lungs he was flipping through channels and Wow Wow Wubbzy came on. She instantly stopped crying once she heard the music! We think she liked the colors and shapes and music. She also loved to watch her brother play guitar hero and would dance to the music.
Today, she is 11 1/2 months old, we let her watch tv in the morning (Super Why on PBS) while she is cuddling with daddy on the couch and half of a wonderpets at night before bed, also cuddle time with daddy. I am able to get ready in the morning twice as fast and can get everything ready for bed at night instead of having a melt down.
We do not normally just put her in front of the TV and the shows that she is watching we interact with her while she is watching them. (unless mommy has to go potty!) She is ahead in her most developmental areas and loves her books more than tv!
I do not think that an infant watching a little TV is going to do anything bad to them unless they are parked in front of it all day... The only thing is that it should not be a babysitter but that also goes for older kids and video games....
