But, Sarah's not real. Nope. She's a doll. Can you believe it? Talk about amazing talent and an eye for detail.
The dolls can come with mechanisms that imitate heartbeats or breathing, or have a warming mechanism so they feel "alive". They are also weighted to feel like a newborn. Because they are so life-like they range in price from a few hundred to a few thousand dollars. They are a collectors dream. But some use them almost like therapy and treat them like a real baby. They dress them and take them shopping.
