Hi Monniemae, it really would be worth it!  A couple of my friends used the one off package and their little ones are sleeping through every night.  Worth every penny.  I think she does seminars too though I have not been to one.  She certainly knows her stuff!  From what she said the whole feeding to sleep issue is pretty common (no surprises there!!) so I bet she'll be able to help.    Strawbs, her website says up to 6 or 7 years I think.    Hope you get things sorted soon ladies, it will be tough but worth it to feel well rested again.
