Bed-wetting in children can happen due to deep sleep, delayed bladder control, stress, or sometimes a family history of the condition. In many cases, it improves as the child grows older. Limiting fluids before bedtime, encouraging the child to use the bathroom before sleeping, and maintaining a regular sleep routine may help. If the problem continues as the child gets older or happens very frequently, it is best to consult a paediatrician to check for any underlying cause and discuss possible treatments.
