hi my daughter is 3 years old she is completely potty trained during day time but has the habit of wearing diapers during sleep I recently stopped wearing her diapers and waking her up every 2 hours during night what I noticed is she is using toilet at least 3 to 4 times between 10.00 to 7.00 can anyone tell me how to stop her using toilet these many times during night time p.s she drinks 2 liters of water daily is it more or sufficient
