Dear mansoor,

I agree that adults (husband and wife) need to have separate applications.
But for children, the parents visa application has an option of 'accompanied' and the visa for one's child is covered within one application itself. I called up the immigration and they advised that as long as the child's name is on the visa, the child will be granted entry. I got my visas issued with no problems/queries within 4 hrs in this manner.
