We cosleep with ours - dd3 has been in with us since she was 2 months old. We have a bed for her in her own room and she starts the night in there but wakes up around the time we go to bed so she sleeps in bed next to me. However before we got her bed, she just took her naps in our bed.

I have had one of the other kids in a side car type thing with the cot, but that was broken when dd2 was 10 months old so put an end to that but it worked well.

At the moment we have dd2 and dd3 joining us in bed at night and ds and dd1 sleep on the floor near our bed on cot mattresses.

We really only need the one bedroom...
