What's your DD in? A cot? Bed?
We still co-sleep, and have a queen size mattress on the floor in the spare room that she sleeps on. I had thoughts of putting her in her cot (which is now converted to a toddler bed I think it's called - one side missing?), but she moves around SO much that I think I'll need to wait until we get her a single bed.

So far it's been working this week. Last night she was super clingy so I just sat right beside the bed. She laid there watching the laptop monitor for a while and just kept touching my arm. But she stayed in bed, and she stayed laying down which is all I ask for, and eventually she fell asleep.

I don't mind if she 'fluffs' about, she's a huge wriggler/mover which is why I'm not trying the cot. And last night she spent a good 10 minutes talking and kissing her stuffed elephant. My only 'rule' so to speak is that she's in bed, and at least trying to relax - lying down.

So far every night she's drifted off because I don't see it happen. I just look over at one point and notice she's asleep.

And the best part is I'm getting my stuff done, so I'm happy.
