DD is 21 months. She has always gone to sleep no problem at 7pm, wakes around 6.30 am and naps for about 2 hours after lunch.
On Sunday night I put her to bed, she settled but woke about 40 mins later and didn't settle until about 11pm. Same thing last night except she kept going until 1 am, eventually fell asleep on DH and woke around 4 am.
Have tried Calpol in case she is teething but it's made no difference and she's fine in the day.
Have tried leaving the landing light on, didn't work either.
Tried leaving her but she just screamed for 2 hours and then was sick.
We don't know what else to try but we are all exhausted, I feel terrible for the neighbours and DD is getting more and more upset.
Any advice welcome please!
