Help with substitute yarn for Berroco Hush

I love making the infant hats that use Berroco Hush (pattern:Moe) but Hush is discontinued. Does anyone else know of a soft yarn that I could use as a substitute?

Thanks for your help!

There’s some on eBay and at bargainyarn.com. But I’d grab it fast. If not, try Allure by Patons, maybe held together with a sport weight if not thick enough.
