It sounds like she's saying, "ur-ee-in." Is that how this should be pronounced?
Sounds fine. You could also go to ivona.com and get 'Welsh, Geraint' to pronounce it.
Would "each one" not be correct also?
I think that would be pob un. Yr un is the one, each one would be the (individual) one and that 'individual' part of the meaning would be said differently. But I'm not a native speaker so..
