Hey Kell, positive thoughts for this mission lol.

We moved house in October and Darcy would have been 16 months old. I figured I might put a big bed in her new room in the new house and see how she went - if it didn't work I figured it didn't matter since we had no time constraints like needing the cot.
However the best laid plans can always be disrupted by a toddler and 3 weeks before we moved, Darcy decided (flat out refused actually) that she wasn't sleeping in a cot anymore. She slept on a fold out bed until a few weeks after we moved and I bought her a big bed.
It was not without issues though. I had major dramas until Christmas so about 2 months and I was letting her fall asleep on the lounge/my bed and then transferring her as it was such a battle and my husband has been away since we moved.
Then one day she just 'got it'. Now I say, let's go and have a sleep, I put her on the bed and she does - same at night.
