Is drinking from a bottle or sippy cup harmful for my baby’s teeth?
A bottle or sippy cup is only a method of delivery, neither is inherently “bad”. However, they both can promote bad habits. Much more important than the bottle or sippy cup is the contents of the container. A bottle or sippy cup with anything other than milk or water is a big no-no. The reason is that it allows your baby to sip as she pleases, often resulting in long periods of exposure to sugared beverages.
