You could do that or make the children point at each other as well - they'll have forwarders to the parents on them and you might as well replicate the root domain DNS zone to all DCs also.

Two DC's are at the parent level and two at the child level. It isn't clear to us what the DNS entries should be the AD controllers. Should the children point to the parents and the parents to each other? Thanks for your help.
