Hi N. C. as challenging as this may be please be reassured this is perfectly normal behaviour for a 4-year-old boy. If you are at all concerned about his wetting then you should certainly have him checked by her GP, while the majority of bedwetting cases result from neurophysiological delay or low hormone levels there are a small percentage that result from some physical abnormality like an overactive bladder, small bladder capacity or a medical issue so it is always important to rule this out first. Unlike toilet training, which is conscious and deliberate, nighttime bladder control is more dependent on maturation of children’s nervous systems and bladder so it is much more challenging to train a child a night. You can encourage healthy bladder development by ensuring he drinks water regularly throughout the day and fully empties his bladder just before bedtime. Time and lots of patience are the best ways to manage bedwetting among young children, remembering that most children stop wetting the bed by the time they turn 6 years of age.
