Some of the mothers, who spoke to the News Agency of Nigeria (NAN) in Abuja on Sunday, said the increase had forced them to consider patronising diaper alternatives.
Mrs Suzzy Yusuf, a civil servant, alleged that although the quality of most of the diapers dropped, their prices skyrocketed.
Yusuf also alleged that most women now sun-dry disposable diapers to meet up with the demand, adding that the prices were discouraging.
