of sentence.

Except as provided in Section 51.1a of this title, no person

shall be sentenced as a second and subsequent offender under Section

has not, in the meantime, been convicted of a felony. Nothing in

physical or sexually related child abuse as a prior conviction for

second and subsequent offender purposes if the person is presently

charged with a felony crime involving physical or sexually related

child abuse.
