Eleanor has become really good with sleeping recently; I put her to bed, she falls asleep independently and generally STTN. However in the last week we have had 4 nights in which she either screamed at bedtime before falling asleep or woke up at night screaming (or both!).
When she does this the only way to stop her is to pick her up or let her hold my hand. In the past if she was sleep trained with GW and usually if she cries a bit I stay in the room without touching her and she settles. However during these episodes she just screams louder and louder, sometimes almost throws up, until I give her my hand. Once she has my hand she'll lie quietly but may take ages to actually sleep. Last night she did this while my parents were over and I ended up bringing her out of her room again. She was absolutely fine, played happily for a while, and when I put her back to bed at 10pm she went straight to sleep, no problem.
I don't know why she's doing this! A week ago we came back from a 4 day holiday in Bulgaria for a wedding, which was rather stressful as it wasn't catered to children. We were in a group and it involved late nights and an erratic routine. However since we've been back she has been back on her routine again. Some nights she'll be fine but she has had these 4 bad nights scattered over the week.
Here is her routine:
7/7.30 - wake up
12 - nap (2-3hrs)
7/8 bedtime
Any ideas?
