My 9 month old daughter use to be a dream going to bed you would just lay her down and she would fall asleep herself. Now for the past 2 months she will scream every nite in her cot till she falls asleep. It ha a only started from she was able to sit up n pull herself up so she's standing. I have to keep laying her down about 15 times till she has exhausted herself from the crying. I don't know how to help her it's only at nite she don't do it when she naps during the day
