If i am normal sized, and have a child with a dwarf, what are the chances our child will be a dwarf?

Depends on type: If your first child has one of the many types of dwarfism, chances of the second child having the same diagnosis depend on the type of dwarfism in the first child. See a genetic specialist and contact "little people of america".

Higher than average: More than 300 well-described conditions are known to cause short stature in a child. Most are caused by a spontaneous genetic change (mutation) in the egg or sperm cells prior to conception. Others are caused by genetic changes inherited from one or both parents. So i would recommend you see genetic counseling to determine the specific mutation. We could then better predict the odds for any kids.

50%: Achondroplasia is inherited in an autosomal dominant fashion. Therefore, anyone affected has a 50% chance of having offspring with the same disorder.
