Am I right in thinking there is nothing you can do to "train" at night and you just have to wait until they start being dry on their own for a while before getting rid of the night time nappies/ pull ups?
DS is 3.6 and still wees most nights. He is (usually) happy to wear a pull up at night so no problems there. Also I have no desire to have to start dealing with wets beds or night time toilet visits. So presuming we just leave everything as it is...?
