trigger populate on Price__c (after insert)
{
List<Price__c > child = new List<Price__c >();
List<Parent__c> parent = [select id,ParentPrice__c  from Parent__c where id in: trigger.newmap.keyset()];
for(Parent__c con: parent)

Instead of Trigger, try using Process Builder. I belive it should be possible using a new Process in Process Builder.

Use the following code and let me know how it behaves
  
trigger customTrigger on Child__c(before Insert, after Insert,
								before Update, after Update,
								before Delete, after Delete){
	
	if(Trigger.isInsert && Trigger.isAfter){
		for(Object__c o : Trigger.new)
			o.Price__c = o.ParentLookup__r.ParentPrice__c;
		
	}
	//Note: It is advised to have only one Trigger per Object.
	//Replace "ParentLookup" with the name of parent lookup field on child object.
}
