I never thought about this until recently, but Charlie's name has 7 unique letters. He writes his name on his classwork several times a day, so he's gotten really good at writing C-H-A-R-L-I-E in both upper and lower case. This has really helped him learn to read and write ~27% of the alphabet!

Olive's name has 5 letters, and sure enough O was the first letter she was able to recognize.

How many unique letters are in your LO's name?
