Hi,
I'm another one to say with both of our boys, it was one of the best things we could have done. As much as I've had to really psyche myself up to do it - and it's definitely not fun listening to them crying, the results within the first day have made me know that it has definitely been a positive step for everyone in the family. Only do it when you're ready to do it. Knowing how effective it has been has allowed me to really enjoy all of the feeding to sleep, cuddles and apparently "bad" habits we've created over the last 9 months . Good luck!
