We took Dd2 out of a cot around that age and when I was pregnant and tired with dS1. We didn't think we could go back, so we fought the good (bad) fight..... It's one of my worse memories as a parent. I have no idea how long the process took to get her to eventually just go to sleep but it feels like months. I SO wish I'd just out her back into her cot and stopped all the negativeness.
