Need disposable underwear for fecal leakage for my 98 year old mom. All diapers are much too thick. Depends Silhouette are tolerable.

My son was a bed wetter. He used pull ups at night until age 12. Perhaps you would get a better fit for Mum if you try pull ups for kids? They were not too bulky and my son was a fairly big kid at 12.

I cannot remember the brand I bought, likely it was Huggies or Pampers, but they worked.
