Tadhg's expanding vocabulary

Tadhg's vocabulary is expanding every week and he is always keen to practice his new words. His most popular words right now are:

• "That" - this is his most frequently used word and is generally accompanied with a pointing finger and, more often than not, a questioning tone.
• "This" - used interchangeably with "That"
  
• "Duck" - surprisingly this is Tadhg's next most spoken word and is used during bath time, during meals (there are a couple of duck's in his bowl) and during general play/reading as any duck, or duck like creature, is spotted
  
• "Dog" - Pijanka is "Dog", also every dog we pass when outside is pointed out as "Dog". Cats are often referred to as "Dog" as well so pretty much any 4 legged animal will do.
  
• "Hot" - generally used when touching a hot radiator or even hotter oven
• "Hat" - often used when trying to pull off Mammy's hat
• "Eye" - a popular word when trying to poke Daddy in the eye
  

Despite repeated use by his parents, Tadhg doesn't seem interested in saying "Mommy" or "Daddy" yet.
