I think the Dex would help - it's a nice soothing rhythmic sound. It's the same principle as using an old winding clock that makes a ticking sound, but believe it or not these are harder to find and more expensive. I buy mine my Dex bears used off of ebay and can usually get them for around $10.00. Since you just hang them on the baby's crib they come in new condition. I think they are about $25 new. |
