Answer is YES. You have already indirectly develop a bad habit on her; i.e. rocking to sleep. Did you swing the yaolan whole nite while she sleep OR off the auto rocker the min she is in deep sleep? If the swinging motion last throughout her nap/sleep time of coz she will cry the minute there are no rocking motion.
My son sleeps in rocker too but we do not have the auto rocker, we will swing the yaolan lightly and stop the min he is in deep slumber. 15-20mins later we will move him to his cot. Initially he will wake up every time we move him, we just put him back to yaolan, swing a while then carry him to his cot. This can happen a few times before he finally settle down in the cot but as time goes by, this does not happen any more.
As for feeling warm, perhaps its the baby cot mattress? My son perspire alot when he was sleeping on Babysafe mattress, even when he is in air con room. After we change the mattress he was ok, still perspiring but not alot and with the fan on only.
To break this habit, you have to be persistent. Do the initial swinging in the yaolan n transfer to cot method, it can take a few days or a few weeks before your baby can adapt but its all worth while. Eventually your baby can sleep on any mattress, even in grandparents or friends house in peace.
