The Horror of Numbers

Teaching Dominic to count 1 to 20 in Filipino while walking to school. 

He's not getting the pronunciations right:

Daddy:  Labing-isa ('eleven')

Dominic: Lagim-isa ('Horror one')

Daddy: Labing-dalawa ('twelve')

Dominic: Lagim-dalawa ('Horror two')

Daddy: Labing-tatlo ('thirteen')

Dominic: Lagim-tatlo ('Horror three')

Daddy: wait a minute...what were you saying?
