Thanks for your thoughts girls.
I had a great sleep last night. I didn't have an afternoon nap and was sound asleep by 9.30!! DH was telling me this morning that when he came to bed I wriggled around a bit in my sleep and he massaged my head until I settled again ... what a darling! And I slept in my own bed. Hopefully I can find a routine that will help me sleep like that more often.
