I don't have any specific tips, and don't want to scare you, but neither of my kids STTN more than once in a blue moon until they were 15 months old. I was an obsessively religious BW EASY tweaker with #1, and a cosleeping "do whatever you gotta do to get through it" APOP mom with #2. Both of them started STTN - BING - at 15 months, like a switch. I am of the belief now that STTN is developmental, like walking, and you can help or hinder but you can't make it happen.
My point is to encourage you, that you CAN do this,you are a good mom, it is OK to ask for help so you can rest, it will get better eventually and it will all be OK. Hugs!
