When my daughter was about 3 she liked to sing "I feel good"
The words to the sing were "I feel good, good, good, I feel good down in my soul, there's something about the love of Jesus that makes me feel good, good, good" (of course I may have them wrong too.
)
She would sing "I feel good, good, good, I feel good down in my soul, there's shukaluka lukaluka Jesus that makes me feel good, good, good"
She would sing it out loud just like she had the words down perfectly.
