Missy123,
My friend, thal children are smart, kind and wise beyond their years. If given proper treatment they do very very well. Send me a personal message, I will show you pictures of my son growing up. You cannot tell whether he has thal or not. He is a bright student, athletic and energetic. I understand your fear, but management is not impossible, especially with all of the new treatments available. There is a good chance your baby will be cured before he begins school.
Please feel free to contact me,
Sharmin
