Swimming with omnipod tip

we've had really good results applying band-aid brand waterproof band-aids to seal over the edge of the pump and cover the adhesive. The pump stays in place usually with no trouble. If my son swims without the band-aids the pump invariably gets really loose and in danger of coming off if it gets bumped. The band-aids work better and are less pricey than some of the medical tapes we've tried.
