Sign it with your own name as the guardian of the minor child. The minor child does not need to sign the note you send. Keep it short, direct and simple.
You don't have to "rescind" the ITIN. Just write a short note informing the IRS that your child with ITIN xxx was assigned an SSN. Then just stop using the ITIN on your tax returns and use the SSN. Keep it simple, indeed.
