Make your toddler go just before leaving home. Carry multiple sets of spare clothes. Use leggings or long pants so accidents are absorbed without a public puddle. For unhygienic public restrooms, hold your child from behind with arms under their knees so their bottom does not touch the seat. A foldable camping potty that fits in a handbag is a game-changer for toddlers who refuse to be held over toilets. For flights over 3 hours, many parents use diapers as backup without guilt.
