yep.. agree with what Tan says...

Consistancy & support each other.

If your partner doesn't go along (which they recommend they do) - make sure you go through the whole process with him, and ensure that he supports you. My DH hated the idea of Shaun crying... but he would never get up in the middle of the night to attend to him. So it was me that was suffering.

It was harder on DH then me when we went to sleep school... but the nurse sat down and explained it to DH and since then - he's been totally committed.

And as Tan says... you need consistancy. No matter what "method" you try - you should do it consistantly for two weeks before saying "this doesn't work".
