How do you stop a baby from opening dresser drawers?

Thinking of buying a large dresser for my DS's room but am worried that he is immediately going to go for the drawers and get his fingers stuck (it is a new dresser and they glide out -- and slam in -- really easily). Have not researched safety at all yet but now that DS is starting to move really need to know stuff like this. Are there drawer locks you can get? If so where? And do they work?

Thanks.

You could get kitchen cabinet drawer latches.
