Wow, whatever next? I would not recommend it at all!
"Award for worst baby equipment of the year must go to US Fisher Price for their "Newborn-to-toddler Apptivity Seat for iPad device". This will allow your newborn (yes newborn – yesterday he was in the womb today he is on the iPad) to experience iPad learning from birth.

By children they mean over twos: the guideline for under twos is that they should have no screen time at all."
