My 3 yr old DD has been dry at night for months and since starting nursery in Sept has started to wet the bed a few times a week. I ve tried lifting her as i go to bed but it still happens. Thought she may just be over tired with school etc but its still happening one month later. New baby due in 4 weeks and she s really excited about it so dont think its that. Nothing else has changed at home. Need help before new arrival!!!!!
