Thanks everyone. OK so here is my strategy:
* Tonight, I put DD to bed 30 mins later (7.30pm)
* We sat down and had a chat about how she is a big girl now and will no longer be having milkies in the morning, it's only for night time. I also explained that we don't get out of bed until it's light outside and as she is now a big girl there will be no more coming into mummy and daddy's bed and if she did wake up early she should try and go back to sleep otherwise mummy will come in and pat her back to sleep in her own cot
* I filled her up with soooo much food tonight
* I put the heater in her room up a little bit and put an extra long sleave top on under her jamies

So... Let's what and see what happens. I have also decided to not let her nap during the day for longer than 2.5 hours. The other day she slept for 4 hours and i think it's cos she was waking up really early!!

Thanks so much for all your advice I will keep you posted on how we go, I am saddling up for a big couple of weeks.
