Yes.  Although it is also possible to order a "traditional" keyboard for
older children, UL does not approve of its use with younger children.

It passes the same test as the original membrane keyboard: 5 million key presses.
Attempts to further thicken the rubber membrane to prevent key tearing could
not pass this number of key presses, leading us to look to alternative ways of
reducing the key tearing.
