My baby girl is almost a year and still does not sleep through the night either. But there are a few things I've come to realize: 1) she's breastfed and still loves that comfort of mommy and 2) mommy & daddy's bed is warmer, cozier, and feels so safe!
I know that not a lot of people agree with the co-sleeping arrangement, but it works with our family. She sleeps half the night in her bed and half the night with us. I tried the crying it out method, feeding before bedtime, no nursing at night--you name it! She was only happy sleeping with us and I was able to get some sleep as well!
Do what is best for your family and as I read the other posts and most agreed that you should pick what would work and be consistent.
Sweet dreams!
