When can you touch the teddy bear hamsters babies?

I would't recomend touching them until they have been alive for at least 16 days. They have to have their eyes open. But be careful! The mom may be very protective, and she may bite. If you touch them before 16 days they mom will eat the baby. If their is an emergancy, burn the bottom of a spoon, to sterilize it. Don't touch it. Make sure it's not too hot though, so blow on it a little bit. Then gentley move the hamster pup back with the litter.
