My just turned one year old was a fantastic sleeper from newborn until about eight months old. Slept through for 10-11 hours from about six months, occasionally waking for a feed. For the last four months she has been atrocious and I can’t recall the last full night’s sleep I’ve had. She wakes at least five or six times a night and immediately screams when waking. Sometimes I’m up more than that. I’m a single parent and can’t share the load. My arms are breaking from holding her and I’m so sleep deprived trying to hold down a full time job. I won’t bring her into my bed as she crawls about and I’d be terrified she would fall out. I can’t function anymore and starting to hate our relationship. Why is it not getting better?
