Let you and your baby take a break from pu/pd. I'm on my second nighttime screamer. It took me 9 mos to get my first dd to consistently put herself down to sleep and make it through the night, and I followed all the rules. (Don't fret, she would get it for a few weeks at a time but suffered relapses from reflux and frequent ear infections). Looking back I was a dissheveled, incoherent wreck!! With screamer and refluxer number 2, I have become a lot more laid back. Sure it goes against everything in the books, but when I learned to cheat and rock my dd calm I ended up catching up on sleep, got more patience, and my ears and jaws stopped hurting from grinding my teeth so much! Besides me, everyone in the house enjoys the little respites to catch up. Each time we start back, she gets quicker at catching on. We do this a lot since she get frequent ear infections too!
