You are a great father. You are the greatest gift to your child.
Don't give up. People do leave DSS/private schools from time to time and there is no reason why you should not re-apply next year or whenever you feel your child is ready to move over.
I feel sure that one day your wish can be fulfilled.
Pikafung - I'm most touched, and could not help but cried when I read your post. thank you for sharing.. and reminding us all not to lose sight of what is important.
