My eastern was gravid twice...the first time she had a litter of 30 and the second time, a litter of 40...not to panic though...garters often have many stillborns in large litters...the first time she did not have any live young...all 30 were stillborn. The second time, only 3 were born live. You should put the babies in a separate tank with a very secure lid, give them a shallow bowl of water that they can drink from and soak in...but that they can get out of, and give them some hides. Feed newborns small meals every 2 days at first and then when they are a couple months old..you can feed every 3-4 days. The babies will be fine together for a while. I am not sure if they will have parasites if their mother has them. Maybe someone else can advise on that. Let us know if you have anymore questions. Congrats!
