Before I get to that let me give you the catalyst:
If you do follow me on twitter or read my blog you will know that we, very successfully, follow the CLB routine (I blogged about it here). Discovering the routine, establishing it and sticking to it has been life changing for us. It has given us our life back. We have had time for each other as a couple, we've been able to have all important time to ourselves in the evening and it brought the night time wake ups down to a maximum of one - sometimes none! It really had changed our lives as new parents.
But - when Jake had colic (and we hadn't realised that's what it was for a while) we gave him a dummy. In fact, we pretty much forced it on him. We were desperate for him to settle, be quiet and sleep. From then on, we gave him his dummy all of the time because we assumed that he wanted it.
All of this was fine until recently -
