my dd2 is increasingly agitated in the evenings, and often doesn't finally settle to sleep until 10pm after writhing about for several hours. my theory is that its some form of anxiety, maybe due to separation, or fear of the dark or something. She seems to settle better with the lights on, and needs to suck madly on a dummy (have tried to see if she's hungry, but she never takes anything). Does anyone else have experiences with this behaviour?
