Isnt she taking speech classes to learn how to lipread? If not, why not?
Most hearing kids that age dont order food at McDonald's..at least my kids dont. At that age, most kids just play with little talking involved.
I have met over thousands of deaf people including those who have no lipreading nor speech skills and they have done fine interacting with hearing people. I have seen personal proof of that with my brother growing up and some of my students who have no speech skills tell me about playing with the neighborhood kids and they tell me how much fun they had.
