Is it okay to let my baby sleep with a bottle?

Letting your baby go to sleep with a bottle is not a good idea. Baby will be dependent on having a bottle to get to sleep in the long run. Moreover, leaving a bottle in your sleeping baby's mouth can cause tooth decay because of the germs that could collect in the overnight milk as well as the teat of the bottle. I have also heard of babies getting bruised because of their bottles. Toddlers might roll around while sleeping with their bottles and hurt themselves in the process.
