We took my dd's bars off her cot a few weeks ago and all seemed to go quite well. However over the last two weeks she has started waking in the middle of the night. She then starts shouting and waking the whole house up. She eventually goes back to sleep but my whole night is disturbed after that. I'm so exhausted now and I don't know what's going on. Has anyone else been through this with there lo? She was such a good sleeper before we changed her into a cot bed. I'm at my whits end now.
