Having worked from home for the past three-and-a-half years in order to spend time raising my daughter, I have learned that children's television programming doesn't have to only provide amusement to the primary audience. There are actually a plethora of programs (including educational ones) which are geared towards a young audience but which adults will most definitely want to sit down and experience with their child. From Sesame Street, to Mickey Mouse Clubhouse, to Sid the Science Kid and beyond, the choices in children's television programming in this day and age are so expansive that there is no reason why a caregiver can't search out a program that will provide them at least a modicum of enjoyment in addition to thrilling the actual target audience.
In fact, I would think that it is far better to keep the adult's attention on the screen as well so that the child and adult can have a discussion following the show about any confusing topics or to recap the lessons that have been imparted by the series. For a show to exclude the adult audience not only makes it harder to convince an adult to turn it on, but also eliminates a great learning opportunity upon its completion. Despite the effort that may have gone into Timmy Time's production, it certainly ends up in that unfortunate territory.
This first DVD release of the series, as noted, comes with five episodes. These episodes run for approximately 43 minutes and there is also a sing-along of the title song available as a special feature. I certainly recommend watching an episode or two on television prior to buying it this on DVD.
