In addition to Dmitry's suggestions.....
If your child zones are being hosted by the child domain's respective DNS
servers, then you may want to use a delegation, You would delegate the child
zone from the parent (or root) DNS server to the DNS server hosting the
child zone. Then you would forward from the child DNS server to the parent
DNS server. Then forward to the ISP from the parent.
255248 - HOW TO Create a Child Domain in Active Directory and Delegate the
DNS Namespace to the Child Domain:
http://support.microsoft.com/?id=255248
The delegation will separate the zone data to their respective DNS server(s)
and may be what you're looking for. In addition, not sure if the child
domains are in another site, but this would add efficiency to the child
domain's DCs and clients so that sort of traffic doesn't traverse your WAN
links.
