My 6 months old has for the past month or so started to wake at least 3 times during the night. At 3 months she was sleeping through but after 2 months of this it suddenly stopped. There has been no other changes in her lifestyle or habits. I recently started solids in an attempt to change her routine and hopefully her sleep patterns but to no avail. She seems to be waking for comforting by being put on the breast rather than actually hunger. I would really like my good sleeping girl back. Any suggestions?
