Hi Alice, it is perfectly normal for your 4-year-old son to still be wetting the bed at night with many children continuing to do so right up to school age. While some children become dry at night a few weeks or months after achieving daytime control for others it can take a little longer. Children�s overnight urine output can be quite variable. You can try and reduce his urine output by making sure he fully empties his bladder just before he goes to sleep and by limiting drinks high in sugar as well as the amount of dairy and citrus he drinks in the evening as these are known to stimulate the kidneys. Make sure he adopts a regular drinking pattern throughout the day. Many children who wet the bed drink small amounts of fluids throughout the day (particularly if they are at preschool), saving the majority of their fluid intake for the afternoon or evening. If you were at all concerned about the amount of urine he is producing I would certainly recommend you consult with your GP.

Regards,
Dr Cathrine
