Thanks for the suggestions everyone:
Heather72 - in regards to the milestone, she started walking 5 weeks ago and also since then the things she has learnt to do have been amazing, do you think this could be disrupting her or is there another milestone I could be missing. Good point on the sensing the baby too I never thought of that.

I have given her a average sized teddy in bed tonight, she seems to really like this one in particular so I will see how she goes with that, if not then I will try that and a night light.
