Have always put ds in the disposable swim nappys and i know they dont suck up water so when he got out pool i presumed he'd weed in the nappy and it stays in the nappy.
However yesterday i bought him proper swim shorts and it says it has a swim nappy attached inside. All it is is a terry towelling type pant bit. Surely this is going to swell up in pool and how will it keep the wee in??
