You have to wait until the body stabilises, no one will ever be dry at night until their levels of ADH increase at night, ADH inhibits urine production, thats why morning wee is normally quite concentrated. That is why most doctors wont see a child for night time wetting until 8 years old.

Jackson was dry at night when he was 4, Melia was 3, Jake isn't dry yet, Jade has been dry for a few weeks now every now and again she will have an accident though.
