My 3 and a half year old daughter had not wet the bed for at least the last 6 weeks. Suddenly, she has wet the bed for the last 5 nights out of 7 and even once during her day nap. She doesn't have a urinary infection and nothing dramatic has happened in her life at the moment to upset her. I haven't changed the amount she drinks or her night routine of toilet, bath, toilet again then bed. Is it normal to have such a relapse? Do I put pull ups on her again or persevere with the wet beds? Love to hear any advice.
