Whatever you do don't touch it the mother will abandon it. If you need to pick it up pick it up with a cloth. If they are really small cover the cage with blankets so they don't fall out of the cage. (Some cages have a wire mesh area in it). Treat them just like the mother guinea pig and the mom will do the rest. Put a bit more food in the cage than usual and refill the water bottle more often then usual. If they get sick take them to the vet as soon as possible. Don't keep them outside if it is extremely cold or hot.
Guinea pigs are generally good mothers, however for at least the first day you should try not to handle the pups to allow them to better bond with their mother. If there is a problem where one is having trouble breathing, like one in the litter mine had, gently pick the baby up with a clean towel and rub it gently but vigorously (even gently massaging the heart and lung area with your fingers through the towel). Replace the pup if it was successfully revived place it near the mother and allow her to take over.
You will have to bottle feed the baby, or try to get them back together. Google that question for more answers, I have found some great solutions that work.
ask a vet or look for info on the web. It may be because of the guinea pigs age.
It's dead
