Does anyone know where I can buy the ear-shaped hot water bottles that nestle on the ears? They used to sell them years ago at a company called The Natural Baby Company, on the same page with the otoscopes and the baby cream. I can't find them anywhere. I asked at Elephant Pharmacy and they said they didn't carry them because heat isn't good for ear aches, but I've found it to be extremely helpful for both my own ear aches and my kids' ear aches. Thanks so much!
