Just that really. My 15mo has gone from generally being pretty good at bedtimd (going down awake and nodding off quickly with no fuss) to screaming when she's put down and bedtime is taking an hour or more. Doesn't seem to make any difference how tired or otherwise she is. She's got a couple of teeth coming through but tonight I gave her nurofen about 30mins before and still she's at it. Any ideas? What should I do?
