I put DD in bed with us sometimes, like if she wakes up ridiculously early or won't go back to sleep after a feed during the night. I know I would be hard pressed trying to get DF out of bed too! Lol.

I sleep next to DF and she is on the other side, between me and the edge of the bed. I have a pillow wedged between the edge of the bed and my bedside table, more for my peace of mind than anything as it probably wouldn't stop her from rolling out. I lie on my right side and have her flat on her back next to me (getting harder as she gets more wriggly...Df always complains she is taking up too much room!), then I put my left arm over her so I can feel if she moves over, and to stop her falling off the side of the bed. The other arm is the 'awkward' arm...wish I could just chop it off when DD is in bed with us..lol. Then I just tuck the doona underneath my right arm and make sure it isn't anywhere near her face.

If DF is away then i put her in the middle of the bed, but he is a heavy sleeper so wouldn't be game enough to put her in the middle when he is in bed.
