Ours started around 9 1/2 months. She'll be a year on the 25th and the only way she STTN is by co-sleeping. But not always.
Â
I have tried EVERYTHING. She has slept in our room since day one, but would co-sleep when sick or teething. I have tried white noise, putting down awake, putting down asleep, hot water bottle, a fleece blanket under her sheet to make it softer, stretched out on top of her sheet to make it even softer, wearing something all day and stretching it across the crib where she lays her head, lights on, lights off and probably a million different things that I can't recall at the moment. Seriously, I've tried everything I can think of.
Â
She has been working on her molars for 2+ months, so this is the problem, although meds do no help at all. None have broken through yet, either. I also think she had separation anxiety (went through it during the day months earlier, but all of the sudden it's a big night problem). She actually went through a period of about a month of screaming in her car seat. I only went out for appointments (we have a 45 min. drive each way). I even eventually asked my MIL to go with me and DD screamed all the way there and back. I had no idea what was going on.
Â
At this point, we're thinking of scrapping the crib and getting her a twin bed, putting the mattress on the floor with bumpers. I wouldn't have a big issue to continue co-sleeping (other than she's a bed hog and I really don't get any sleep), but I'm 35 weeks pregnant and she's a high needs baby, using any excuse to wake up. A crying newborn would be a great excuse.

Hopefully yours doesn't last this long!!
