I have a very early morning waking DS (a year now of 4.30-5.15am) and have run out of ideas on how to get him to sleep longer - not only does he wake up early but he screams and screams until I go to him no matter how long I leave him - so I was now thinking if he could play in his room he might be more relaxed? I wondered if 20 months was too young to go into a bed?
