hey dilema,
i know exactly how you feel i used to go to work for a full night sleep. i worked in residentail care and the teens i looked after there knew they had to literally be dying before waking me in the night. None of the other staff could work out why the only night of the week everyone got a good kip was when i was on shift. Heartening to know obnoxious teenagers can have a heart.
My ds will be 5 next week and still has one bad night a week he is better since being at nursery 5 mornings and 2 full days a week at childminder.
go to a hotel and sleep.
get a bigger bed we now have a kingsize and was the best thing i ever did. We also have 2 single duvets, 1 for me and 1 for DH and DS. Turf dh into her bed when he is there to.
my son is under a peadtrician for other non sleep related issues but when we discussed it with him he said if it was still an issue when he was at school he would refer us to a sleep clinic but we would have to be prepared to entertain medication if it was worth doing.
you are not alone.
It does improve tho she will not still be in your bed when she is 12.
