Help with sleeping

Does anyone have any advice for how to get a 9 week old to sleep? During the night (touch wood) we don't have any issues just during the day. It seems the only way I van get him to sleep is by feeding and even that does not work all the time. I know he is tired so put him down but he just cries and sometime screams. I'm wanting to try and establish some sort of routine but am finding it impossible at the moment. I have researched about sleep training and have tried various ways but nothing seems to be working.

Has anyone had similar issues and if so any advice?
