I can't offer any first hand advice, as we've never done pat/shhh for sleep training. We did a lot of AP, but have an angel baby and were able to transition to independent sleeping fairly easily and quickly. BUT, I have read that many times there is an "extinguishing" effect whenever you change a habit (not only for babies, but adults as well) where you implement something new such as sleep training/ shhh/pat, and things go ok for a few days, then it all goes down the toilet, because the baby thinks -"I'll give it one last shot and see if I can make mom crack, and make her go back to the old/familiar way of doing things and rock me to sleep again". So if anything maybe see if you can stick it out another day or two, and if it doesn't get any better then try another route. I know you are supposed to "start as you mean to go", and avoid AP if possible, but I do completely understanding needing to do what you can to get your baby to sleep at some point in time so their crying doesn't completely make you crazy. I hope things get better, it is so great when they can get to sleep on their own, helps with your own sanity so much!!! Good luck!
