My DD is 11 months and for ages has slept 12 hours a night- 6.30-7.00am. Her nap is 9.30-11.30, then that's it til bedtime.
What's happened over the last week? She often wakes suddenly at night, screaming for 1/2 hours, and her nap no longer exists but she is SO shattered she's miserable. Her brilliant routine has just gone out the window.. Any tips?
