The bit that got me was that there was a bit in there that says something along the lines of... some children will go to lenghts of vomiting or pooing just so they dont have to go to bed

Now if my child was that destraught that they were vomiting or pooing and all i was doing was cleaning them without a word and repeating the process until they 'learnt' to go to bed, i might have a fantastic sleep at the age of 2 but seriously YOU CHILD IS VOMITING ITS THAT DISTRAUGHT!!!! what emotional scars will i have given her in the process????
after that sentance i put it down and i have never opened it again!

Mj just turned 2, she still sometimes wakes (more than once a week), i learnt that she needed a bedtime routine as in bath/play/story/feed/bed but thats about the cues and these are talked about by many 'experts'... Try not to get caught up in the fact that some babies are sleeping through, cos most REALLY are not.
Approach it in a calm manner, remind yourself everyday that there will be a point that your child sleeps all the way through the night (not many partents to 5 yo that have to settle their child back to sleep every night!) and that you will have helped them develop a great attitude to sleep by not forcing them to sleep. It is an evolving process, what i do now was different to 6mths ago, and very very different to that when she was 6mths old. learn together and try and approach without anxiety or stress as your baby will pick up on this.

People that write books are not experts, they just have been able to publish a book, if i tried hard, i could do the same - doesnt make me an expert at all.

Oh and dont compare or talk about what you are doing (other than in here), it only give people the oppertunity to criticise!!!

Good luck
