M: Shaking an infant out of anger or frustration can lead to a severe brain damage, even death. A New Jersey company called Bouncing Babies is making it safer than ever to shake your baby. Joining us now is the founder of Bouncing Babies, Kelly Timmons. Hi, Kelly.
    W: Thanks for having me.
    M: Kelly, tell us about this amazing product you’ve created.
    W: Well, it’s called the Baby Safe Ball, and it keeps your baby one hundred percent safe, no matter how hard you shake him or her.
    M: Yeah, well, it looks like it will make a great shower gift.
    W: Oh, yes. It’s perfect for first-time mothers, and I also recommend it to daycare centers or babysitters, anyone who’s working with a newborn.
    M: Right, wonderful! So, show us how it works.
    W: Well, it uses a technology which keeps the baby upright no matter how you shove or throw it.
    M: So the baby’s neck won’t snap under the weight of its skull being thrown back and forth.
    W: That’s right, exactly. And on the outside, it’s got a thick layer of break-resistant material. So you can throw this thing against the stone wall and it won’t crack.
    M: OK. Oh, it’s actually quite light.
    W: Yes, and it’s sound-proof, and there are clowns painted on the inside.
    M: You know, Kelly, we have had a volunteer’s own baby Sam to be used as a demonstrator, so you can show us exactly how the Baby Safe Ball works.
    W: I’ll be glad to.
