How to feed baby guinea pigs milk !!!

The mother of these three little guys died two weeks after their birth and do not know why. So as a result I knew I needed to give them milk because they didn't eat food yet. I fed them normal cows milk such as the one someone could buy at the store. Then used an eye dropper to give them the right portion of milk as if they were drinking it from their mother. THANKS FOR WATCHING !!!
