At some point Hyrum stated saying a wonderful phrase that eased his mother's heart. The phrase is "OH, YES". He says it with much feeling and determination as a regular response to anything he agrees too, or at least he did. As any parent of a two year old feels that if they ever get over saying No all the time it would be wonderful and just figuring out that there is a yes is awsome.
Lately his favorite response to most questions is "OKAY" that is supposed to mean a lot of things, like Yes, lets do it now, what are we waiting for or of course.
