It can feel just awful some days waking and feeling more tired than when you went to bed. For me (DD2 also woke 5 times a night till she was about 16 mths) after i tried everything i wanted to try to change it, i just gave in one day. I accepted i couldn't do much more and that it would get better in time. And eventually it did. The emotional relief that gave me (making peace with the wakings) was HUGE!

Other things that help are 1) don't look at a clock in the night 2) don't count how many times you get up. I really don't keep a track and when people ask how often i'm up in the night, really having no idea of how many times is a relief in a way (although it's probably about 3 times at the moment).

Hope you get some sleep soon.....
