Care for a female guinea pig when babies have died?

How Terrible!! =[ If there are any other nursing guinea pigs around, they will nurse babies that they did not give birth to. Whenever something like this happens, you need to find a really good pet store and veterinarian places to provide nutriton to the babies. Whenever my guinea pigs have babies and find out something like this happened to somebody, I myself would take care of the babies that lost their mother and then return them to their owners. Anyways, it doesn't take long at all before guinea pigs start to eat solid food. They are born with teeth just like they are born with hair.
