Hi!
When my daughter was about 4-5 months old, I started using techniques I found in Elizabeth Pantley's No Cry Sleep Solution book. I had to be consistent with my methods, but it definitely worked. I found that it was hard to digest the whole book (especially being so tired), so I focused on a few techniques that seemed do-able to me or that seemed to really speak to my daughter's particular difficulties - and this worked very well for us. I also felt uncomfortable with any CIO plans. Pantley's techniques are very gentle but effective! Good luck!!
