My 11mo ds seems to have given up on sleep. A few weeks ago he would go down at 730, have a bf around 11 then wake at 6am. I could just about cope with the occasional night wakings/4am starts. Then he had a cold and for two weeks now has just not slept. He screams every time I put him in the cot (day or night), will not settle til 10 pm or later and wakes multiple times. Co sleeping hasn't helped, he is just as unsettled. Has anyone got any useful advice as we are struggling to function at work now! Tia
