What Karsten says these days

Seems like every few days Karsten says something new. His new words are:

• Shoos (aka shoes)
• mmmball (we're not sure if this is 'my ball' or just 'ball' with an extra syllable)
• neigh, baaaa, mooooo (usually said in response to the correct animal)
• This
• Dat (aka that)

Where did my baby go - he's starting to become such the little boy!
