Hi there, my son is 2 and leaking out the top of his nappy at night. Seems to be that his penis is becoming erect overnight making the urine spill over the top of the nappy. Any suggestions?

Dear Meredith, how frustrating! Leakage can sometimes result from improper fit, which can occur if your son’s nappy is too large or too small. Check that they are fitting him properly around the leg. You also need to ensure that his penis is pointing down as this may result in urine leaking out the top of the pant. You could possibly try using plastic outer pants to stop the urine reaching the sheets. If you were at all concerned about the amount of urine he is producing overnight I would certainly recommend you consult with your GP. All the best!
