question about whistling from hearing aids

Dear Mrs. Newton,
Feedback is a way of life with little ones, and I applaud you for realizing how important it is to get a good earmold fit and keep amplification on your child. You might purchase some Otoease from your audiologist to coat the ear canal part of the mold. The purpose of Otoease is to make earmold insertion easy when there is a tight fit, but by coating the earmold, it can help with some of the feedback problems.
Also, if the new earmolds are even slightly loose, ask the audiologist to immediately have another set made and to "double dip" them. This means that the manufacturer will dip them a few times to make them a bit thicker (and therefore tighter).
How to get a good earmold impression from a squirming, protesting baby..... that's a good question. Does Meadhbh sleep soundly? I've often made earmolds during naptime in a quiet, darkened room with the little one snuggled close to mom. And always I do one ear at a time rather than trying for both at once.
I hope this information is helpful. Let me know if the Otoease helps. And good for you for trying to keep on those hearing aids!
Sincerely,
Kathleen Sutherland
