9mos DS will not sleep in the evening, unless in bed with me, nursing constantly.
He is EBF and co-sleeps, until now he has slept in his cot from 7-10, but is now refusing to do this and instead screams when I put him down.
I've read 'no cry sleep solution' and it did work but now he can stand up all he does is stand and shout instead of sleeping.
I'm exhausted 
AIBU not to know what to do? Should I call the HV? what books can I read. Please help me
