wants me to get a wee sample in this tiny bag JIC he has a UTI. How the heck am I supposed to a) predict when he's going to pee and b) manage to get it in a bag????? Anyone had to do this and have any tips on how not to end up with a grumpy nakey baby and pee everywhere? Should I just tape it to his crotch? lol

it should have a sticky thing on bag you place genitals in bag stick to top, place nappy on a check regularly
