I swear this is what I see when I look at him, even now.
Even so, his last baby remnant -his lisp- is slowly leaving us... with a little professional help.
And man, is she good! I had been casually trying to get him to make the S sound for at least two years, and his speech teacher helped him to do it the very first day.
Since that first lesson, he has been so determined! He still slips into his sweet old way at times, but I hear him working hard to articulate correctly almost all the time now, even on the playground and arguing with his brother!
