Can I Put My Baby to Sleep With a Bottle?
As far as dental hygiene is concerned, this a habit that you would ideally avoid. Unlike when you give a child a bottle during the day and they digest it before sleeping, if you put a child to bed with milk or juice—especially an older child who does not need it for sustenance but has just grown accustomed to it—the sugars in that drink will sit on their teeth all night and can cause cavities.
If it makes you feel any better, we have to give adults who go to sleep with cough drops the same news. When you go to sleep, you want to avoid any sugars coating your teeth all night long.
