Dd2 has never been the best of sleepers (in fact neither are). We did the tresillian thing when she was a baby and I HATED it and vowed I wouldn't let her go to sleep like that.

Her sleep is getting worse though. Last night she went down at 7.15pm and went to sleep at about 8pm. She woke t 12.30pm and was so unsettled. I don't think she was awake. She wriggled, moved, was talking but I couldn't make out what she was saying and would lay there with her eyes open. This went on until 4am. I spent the majority of the night laying with her to try and settled her - albeit with no sleep. It was until about 4.30 she went back to sleep. She then was awake at 7.
This is becoming more and more frequent. I'm exhausted with being awake all night then working but it has to be done. She's tired because she's not getting enough proper sleep.
At why point do you do something else? What can you do?

Both girls have a bedtime routine, they have a nightlight, I use rose oil. I don't want to resort to phenergan again. I need other suggestions.
