Hi,
load map as following 
Map<id,list<contact>> accountRelatedContacts = new Map<id,list<contact>>();

for(Account acc : [select id,(select id from contacts) from Account]){
	if(accountRelatedContacts.get(acc.id)==null)
		accountRelatedContacts.put(acc.id,new list<contact>{});
	if(accountRelatedContacts.get(acc.id)!=null)
		accountRelatedContacts.get(acc.id).addAll(acc.contacts);
}
