I have no advice.... But I feel you pain!

DD has never slept well, and some days I feel like I am in groundhog day.... It gets to bed time and I just don't know if I have the strength to do it all for another night

Then I go to mothers group and someone tells me they are "so exhausted" because their kid woke ONCE in the night and they usually sleep twelve hours.

I am just repeating to myself what I read in one of the millions of baby books I had read " poor sleepers are really just highly intelligent, they find it hard to switch off". So our children are geniuses!!!!! Lol
