nank you

I was discharging a student from special education/speech therapy today. His mom shared with me that this morning when she informed him that they were coming to see Rachael because he was graduating with speech he decided to say everything incorrectly. At the end of the meeting my 3 year old student’s mom gave him a card and told him, “Can you give this to Rachael and tell her Thank you?” He turned to me and said, “Tha…, nank you.” He then turned to his mom laughing and said, “Mom, I almost said Thank you, but I changed it to Nank you!”
