Pampers splashers and other swim diapers are only designed to keep in the poop when swimming.
Swim diapers including pampers splashers will not absorb urine or water so if your baby or toddler wears the swim diaper when not swimming and they pee in the swim diaper the baby or toddlers pants will get wet.
You'll need normal diapers for your baby or toddler to wear when not swimming.
