Prob' bly

Travis is beginning to talk quite a lot more now, and some of the things he says are funny, even without his meaning them to be.
We were outside looking at chipmunk holes, and Travis said "He's in 'ere, prob' bly sleeping".
Then he said "I step on a buggie. He's prob' bly dead." I replied "You're probably right!"
It was just so funny to hear this two year old using a word like "probably" in correct context, when sometimes he says things I still can't even decipher!
If night is coming, he will look out the window and say "It's ge' nin dark". He pronounces ketchup like "kep chup". He's more concerned with making his point, that being grammatically correct!
