The early 1990s also saw the introduction of gender-specific diapers in the Pampers brand; the product returned to unisex diapers towards the end of the decade. In 1993, Pampers introduced training pants, but the Pampers Trainers were a short lived product. Pampers did not sell training pants again until the introduction of Easy Up. In 1996, P&G acquired Baby Fresh wipes from Kimberly-Clark; Kimberly-Clark had recently acquired Baby Fresh owner Scott Paper Company and was ordered to sell the wipes business. In 1998, Procter & Gamble introduced its largest diaper at the time, Pampers Baby-Dry Size 6. It was promoted in an advertising campaign featuring pediatrician and child development expert Dr. T. Berry Brazelton, who said to let the child decide when the time is right to potty train. The size 6 diapers were billed for growing toddlers. Huggies also introduced a size 6 diaper at this time.
