Yes, u understand and no, u don't know what it is like to live a life as a deaf person. U really do understand the visual needs of dhh children especially the importance of language devlopment during the deaf child's first 5 years of life and how those years impact the child's academic future.
I wish I can explain more cuz I have a lot more to say but I am so exhausted and busy with returning to work and starting with my new class in addition with the responsibilities of a new house and kids. Internet is still not working. 
Maybe next month when things settle down at work and with the house, I will be on more.
