Better With Inflection Than Actual Words

When Declan is looking through his toy box and pulling different toys out Daddy always says "Hi Elmo" each time Declan lifts Elmo out of the box.

Today Declan takes Elmo out and immediately says "ahhh eh eh". That's right. He mimics inflection rather then actual words. 

By careful attention we 'get' what he's trying to say or as it would appear to others; yes, we understand 'baby talk'.
