Pull-Ups is a brand of disposable diapers made under the Huggies brand of baby products. The product was first introduced in 1989 and became popular with the slogan "I'm a big kid now!" The training pants are marketed with purple packaging: boys' designs are blue and currently feature characters from the Disney Junior show Mickey Mouse Funhouse; girls' designs are purple with the Disney Junior show Minnie's Bow-Toons characters.

Huggies Pull-Ups have been distributed in 4 different types which have been intact since 2011. (not counting the renaming of Wetness Liner.)

In March 2005, the original Huggies Pull-Ups were renamed Learning Designs after the small pictures that fade when they become wet.

Wetness Liner Pull-Ups Training Pants were first distributed in 2005 as a competitor to the now defunct Pampers Feel 'N Learn. These Pull-Ups were much like Learning Designs Pull-Ups, except they added special liner to the Wetness Liner ones. This liner is placed on the inside of the Pull-up, where the wearer is most likely to wet, and is sensitive to urine. When the Wetness Liner is exposed to urine, it causes the wearer to feel uncomfortable, and learn that they shouldn't wet themself and should use the toilet instead. Wetness Liner Pull-Ups also have the Learning Designs, which also fade when the wearer wets the pull-up.

In 2006, the Wetness Liner Pull-Ups were replaced by Cool-Alert. This variation has been intact since.

GoodNites are used to control bedwetting. In 2008, The GoodNites disposable underwear split up from the Pull Ups brand merging with the Huggies brand, Then in 2011, GoodNites split up from the Huggies brand and formed their own brand which is the same name as the product.

At the same time that Wetness Liner was renamed Cool Alert, Pull-Ups introduced Night-Time Pull-Ups. The Night-Time Pull-Ups were very much like a regular Pull-Ups pant, except it has more absorbency, and they have bedtime designs featuring Toy Story characters for boys & girls. The Night-Time Pull-Ups are not available in the 4T-5T or 5T-6T sizes.

The main use for Pull-Ups Training Pants is as an aid for toilet training toddlers and to help them learn not to wet. Although up until 2000 Pull-Ups Training Pants were nothing more than diapers that go off and on like underwear, since 2000, there have been several changes to them. The first one was the addition of magic stars/flowers (now known as Learning Designs on March 2, 2005) on the inside only in 2005-2007 and front of the pant that fade when the wearer wets it as a way of discouraging wetting, and as a motivation to stay dry in time to make it to the potty, and if the wearer stays dry, the stars/flowers will stay on the Pull-Up. Next was the addition of Easy-Open sides. These made it so that the sides of the Pull-Up still go off and on like underwear, but enable parents to easily open the Pull-Up to check to see if the wearer soiled the Pull-Up, or to quickly change a messy Pull-Up. Though many enjoy this feature, some parents have criticized this feature for causing the Pull-Up to rip too easily.

The Cool-Alert Pull-Ups had a controversial issue regarding that the wearer likely will either get a rash or not feel the cooling effect when (s)he wets the pant. The 2009 Potty Dance commercial had aggravated parents due to its suggestive dancing, mainly, when the toddlers put their hands on their genitalia and make circular motions with their hips. This has been pulled from airwaves and replaced with a more appropriate version by Ralph's World, which replaces the offensive movements with sidesteps.

Ever since Huggies Pull-Ups became popular, several other brands tried to copy their product. The first competitor besides store brand training pants were Pampers Trainers made from 1993 until 1995. In 2002, Pampers introduced "Easy Ups" training pants. The Pampers brand also had training pants with a wetness liner called "Feel 'N Learn" which were made from 2004 until 2007. Luvs also had a line of training pants made in the 1990s.

Pull-Ups are the official sponsor of ESPN Radio's coverage of Major League Baseball, as well as Westwood One's coverage of Sunday Night Football, and on many terrestrial broadcast television stations and children's TV brands, including Nickelodeon, Disney, Cartoon Network, Universal Kids (formerly known as (PBS Kids) Sprout), etc.
