Swim Diaper and Trainer Patterns

Swim Diaper Patterns are used to make re-usable swim diapers for infants and toddlers. See our article on swim diapers here. Even families that do not use cloth diapers like swim diapers, and re-usable swim diapers cost a lot less than the disposable version. Swim diapers make a great gift!

Trainers are similar to a swim diaper. Trainers have a little absorbent material inside, but otherwise trainers are mainly a waterproof shell to help protect clothing in case of an accident. A trainer should be easy for a child to pull up and down, as the child is learning to use the toilet.
