Hi, you, it's pretty normal to feel bad when accidents happen in bed, especially when the big day is soon. Wetting the bed is medically referred to as nocturnal enuresis, which is when an individual pees during their sleep without consciously doing it. This condition might be caused by genetic factors, small bladder size, stress, or hormonal imbalances. The good thing is, that bed-wetting usually resolves itself with time as the child grows. To help manage it, you can, first and foremost, cut down the amount of water intake before going to bed. And besides that, you are not by yourself in this, which means make it a solvable problem.
