We try for 8pm bedtime but lately ends up being 9-10 before she’s down. Normally wakes up anytime between 6&7
Does she have a nap? I'd say that bedtime (8pm) is too late especially if no nap. If there is no nap I'd aim for bedtime to be 12 hours after waking as by the time you are getting to 13-14 hours they are overtired so it's not necessarily that they are refusing it's that their cortisol levels are so high they struggle to switch off.
What's the timings for wake up, nap and bedtime?
