I want to show the stock status of child product when the configurable option is selected in the frontend.

For example product C1 has S1 ( 1 qty ) and S2 (10 qty ) children. "Only X left Threshold" is set to 5. So when user selects S1 option, it has to show the message "only 1 left", if S2 option is selected then no need to show message as its qty is more than the threshold set.

Answer 1

$_product is your configurable product.

To get all its simple use :

$_product->getTypeInstance(true)->getUsedProducts ( null, $_product);

So you might have something like :

foreach ($_product->getTypeInstance(true)->getUsedProducts ( null, $_product) as $simple) {
     $stock = Mage::getModel('cataloginventory/stock_item')->loadByProduct($simple)->getQty();
     echo $simple->getName()." with size ".$simple->getSize()." have a stock of $stock";
     echo '<br/>';
 }

For M2

$_product->getTypeInstance(true)->getUsedProducts ( null, $_product);

So you might have something like :

foreach ($_product->getTypeInstance(true)->getUsedProducts ( null, $_product) as $simple) {
     $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 
     $StockState = $objectManager->get('\Magento\CatalogInventory\Api\StockStat‌​eInterface');
     echo $simple->getName()." with size ".$simple->getSize()." have a stock of " . $StockState->getStockQty($simple->getId(), $simple->getStore()->getWebsiteId());
     echo '<br/>';
 }
