Amber Cove - age limit?

[DoubleDeuce]

I am trying to book a shore excursion for Amber Cove through Carnival. It will not give me an option to buy a ticket for my 1.5 y/o daughter. Is there an age limit where children are free, or is there a glitch in their system?

 

Thanks.

In the description it should say if there is an age minimum requirement or if kids under a certain age are free.
