if you are using lightning component, you can use onchange="!c.functionName" or same thing in VF also  on lookup field selection.

called function will have logic to query the child details and  render them on lightninig component or vf page

You can use force input field to render lookup.
<force:inputField aura:id="accLookup" value="{!v.account.LookupField__c}" />
on change of lookup , you can can call lightning controller method using this.
<aura:handler name="change" value="{!v.account.LookupField__c}" action="{!c.queryChildern}"/>
queryChildern : function(component,event,helper){
    // write logic here to fetch details from backend 
   //call apex class method here

I dont have any sample code right now but hope this logic can help you..
