My DD has always been an AMAZING sleeper!!! The only time we've ever had issues is if she's sick or teething, which is to be understood. When I put her down last night....a temper tantrum to end all temper tantrums ensued. She had a complete meltdown. I tried to let her CIO, but ended up rocking her to sleep. She woke up my mother in law, and I felt so bad. I had to do something to make her quiet. Tonight...same thing. I don't know if it has anything to do with my new work schedule. I'm gone most of the day. I see her for a few hours in the morning, and then I'm home in time to put her to sleep each night. Is it even possible for her to be associating bedtime with mommy leaving again soon?? Or is this completely typical behavior for a 9 month old??
