There are other places than the bed for DTD. Normally we wait till she has gone to bed and use the lounge room, other than that we move her into the cot (that is set up as a sidecar) and just be quick and quiet.

I agree with Caro though, having a kid just makes us a bit to tired to be DTD that often anyway. Even if she was in her own room, I doubt we would do it more often.
