Bonds for deceased son.

My mom bought my son about $1400 worth of bonds. It's issued in his Social Security number and underneath that WITH me.

Eg. John Doe 999-99-9999 WITH Mary Doe 123-45-6789.

My son passed away in 2008 (he was only 4) and I would like to have the bonds directly re-issued to my daughter (now 23) so I don't have to cash them and incur reporting it as interest. I waited on hold with treasury direct for a long time only to be disconnected.

Does anybody have experience with this?
