Hm my boyfriend wants to get them, but I'm sticking with the musical CDs only. I watched a news segment on how TV, even baby-oriented videos like Baby Einstein and shows like Sesame Street, can be overstimulating for babies/toddlers.. however Sesame Street has been proven to improve school-readiness in the 3-5 year age group.
Because that study makes sense to me, and because I'm not overly excited about watching Treehouse TV all day long.. I don't think my LO will be watching TV until she's older.
