Does anyone have experience sleep training an "older" infant? I have been nursing 10-month old Zoey to sleep and rocking her when she doesn't fall asleep nursing. Lately, I've been rocking her more and for longer periods of time. I think it may be time to try sleep training again. The last time we tried, she was 4 months old and she cried and cried and cried...and then cried some more, so we scrapped it. Is she too old? Am I destined to burn a hole in my carpet from all the pacing? Would love any tips or advice!
