LO is 5 months old and has been waking up 8+ times per night for over 6 weeks now, with only a couple decent nights thrown in. Sometimes it's easy to get her to go back down, other times someone ends up staying up with her for an hour. She was never a good sleeper to begin with so our sleep deficit is huge. We've tried co-sleeping and non-CIO methods and they haven't helped. I have been battling illness after illness since I am so run down. DH and I both work full time and our jobs are suffering. We have really reached the end of our ropes.
Our pedi gave us the green light for sleep training and actually recommended Weissbluth's extinction method, but DH and I decided we'd prefer to try Ferber's method (with checks) first. We were going to wait until the weekend, but the situation this week has been so bad that we are now going to start tonight.
Just looking for support, or any tips/advice if you have used CIO successfully.
