My 7 month old has had the same sleeping routine since she was 2 months old. In bed by 830/9 and awake between 5/6 for a bottle then back to sleep for another 3-4 hours before starting her day. She would also put herself to sleep at night. I would simply lay her in her crib (awake) and she would put herself to sleep within minutes. Well this has stopped!!! For the past 5 days she cries when I put her down and will only fall asleep in my arms... she is teething and I am not sure if this is the reason for the change or if she is starting a new bad habit. Has this happened to anyone else?
