Ds is 9 months. Over the last week or so he has started to wake regular as clockwork at 3.15am and it takes best part of 2 hours to get him back to sleep. He doesn't cry or fret once I'm with him, but lies in my arms quite calmly and wide awake. The first night it happened I eventually gave him a bottle and he soon went back to sleep but I am loath to do this again as I din't want him to wake for the milk. He hasn't been fed during the night for months so don't want to go backwards. Any thoughts / ideas?
