DD is 6 months old and sleeps in a cotbed in our room. She is exclusively breastfed and wakes 3-4 times per night. I'm not entirely convinced that this is always due to hunger but it's so easy for me to sit up in bed and semi-doze whilst feeding her back to sleep.
However, DH is also disturbed and has suggested that moving DD to her own room might improve her sleep as perhaps we're all disturbing each other.
Not sure if I'm convinced though and I'd be interested in hearing other people's experiences.
