I'm at my wit's end. Almost every bedtime for the past 6 weeks DC2 (age 3) has gone completely giddy as soon as it's lights out. Giggling, jumping up and down on her bed, running around, climbing into DC1's bed (they share a room), pulling hair, turning lights on etc. I carry DC2 back to bed, calmly say it's sleepy time etc. Occasionally it works and DC2 calms down but it can often take over an hour, during which time poor DC1 is kept awake and I inevitably get fed up and end up shouting and then feeling guilty about it. To make matters worse DC1 is an early bird so wakes up by 5.30 most days even no matter what and is therefore losing sleep by being kept awake.
I think long term we may need to move DC2 into the box room (once we've cleared out all the junk that's currently stored there!!) but for the meantime does anyone have any suggestions for how to make bedtimes calmer??
