My JR is 2 1/2 years old, sleeps downstairs in the lounge, never had any problems with him sleeping untill recently. Now he howles as soon as we go up to bed, scratches at the hall door to get out, but when I get up and go downstairs he will lay down and go to sleep. I am spending more nights sleeping on the couch because I do not want him waking the children or the neighbours up. Why is he suddenly acting like ths, what can I do.
