How to communicate with people who stammer

Here's a few tips on how to effectively communicate with somebody with a stammer:

1. Let the person who stammers finish their sentences
2. Stammering is a communication difficulty and not a mental disability
3. Just treat people who stammer like anyone else – allow them time to talk 
4. Keep eye contact with them – it helps
5. Focus on the content of what they are saying, not the stammer.
