My 7wk old baby barely sleeps at night, I feed him around 10.00pm he doesn't sleep until around 1 and then is awake at 3 then at 6 then wants to stay awake then, he also struggles to fall asleep alone, usually we have to get him to sleep and then put him into the cot 9 times out of 10 this wakes him up, he sleeps well in our bed which I resort to if I'm too tired but I want him to sleep on his own. Any ideas?
