PoppyStellar I am sorry this is so hard.
Our birth dd was a terrible sleeper and came into our bed right up until about age 9 when we adopted ds (then 3). Somehow just before he arrived she felt fine to stay in her bed on her own. She is quite a nervous child and was very bad at sleeping.
Is the emergency bed a camp bed? I think you are right to let her sleep in it (I am assuming you don't call it an emergency bed to her!). One day I think she will discover her own bed is bigger and more comfy than the camp bed!
Here are a few things that might help (sorry if you have tried them):
-talk to dd during daylight about how things are and see if anything is bothering her, don't make this talks part of bed time routine because that can be used to elongate bedtime!
-make sure she is happy with light on or off, door open or closed, even my 11 year old has views, having curtains closed sometimes scares her! (She is not adopted and I have no idea why this bothers her, there doesn't need to be a sinister reason for this.) Again be careful not to do too much of this during bed time as it can be a tactic to elongate bedtime routines
-make sure the room is comfy - the weather has been very changeable and kids can sometimes get very hot at night, they are not good at regulating their temperature sometimes, make sure the room is the right temperature for her
-warm milky drink before bed (before teeth cleaning obviously) - in hot weather cool milk, although I do feel warm helps sleep!
-warm bath - in hot weather cool bath, although again I do feel warm helps sleep!
We do the bath time routine nightly, I am sure you do. We do it every night except when coming back from being far off, e.g. meal out of whole day outing after dinner, we usually put kids in pajamas in car
Other things could help
- things like lavender can smell great and make people sleepy (as long as they are not allergic to it) e.g. in bubble bath, in room diffuser
- if she will not sleep but is not distressed give her picture book, or a reading one if she can read now, my 5 year old can, my dyslexic dd never could at that age but some kids can
-sometimes the pressure to 'go to sleep' is quite hard on kids. Easier to say 'lie down flat', I always used to say something like 'flat as a pancake'
I'd ask dd to plan something in her head.. our next holiday, if she owned a zoo what would it be like
-if your dd likes baking or decorating cakes get her to plan in her head the most yummiest cake or best cake decoration
In order to get some 'me' time I would be tempted if you have one or can afford one to use a small screen lap tap or whatever that you can see and she can't and headphones so you could be doing emails, or watching a film or something on the bed, while she is on the emergency bed (which I am guessing is lower than your bed so below her line).
When we go away to a hotel we are all in a room together, me and DH, dd 11 and ds 5. Ds gets so excited and cannot get to sleep he tosses and turns and gets quite frustrated. We just encourage him to lie still and close his eyes. I think saying a lot of times 'go to sleep' doesn't help. How does anyone make themselves do that! But I am sure I have said that at times!
Good luck.
If my advice is rubbish, please ignore BUT you are no way a rubbish mum.
