By allowing this seemingly minor indulgence, Tom and Katie could cause their precious daughter to suffer both tooth decay and emotional stress, doctors told The ENQUIRER.

Pediatricians generally want toddlers to drink from a cup by their first birthday.

Exposing a baby’s teeth to sweet liquids over long periods of time can result in “baby bottle tooth decay,�? warn experts.

“Liquids containing sugar- including milk, formula and fruit juice- if left in a baby’s mouth, can acidify and become corrosive to the teeth,�? pediatrician Dr. John Sterling, who practices in Vancouver, Wash., told The ENQUIRER.

“If the baby lies in bed or sucks on a bottle for long periods of time, both the upper and lower teeth can be subject to decay,�? said Dr.Sterling, who does not treat Suri.

“Toddlers can become dependent on it and on the ‘sucking impulse,’ which is often difficult for them to control and to wean themselves off of,�? Dr.Kuemmerle, who does not treat Suri, told The ENQUIRER.
