We've seen Suri Cruise [1] tote her bottle around town since she was a wee one and many other tots still hit the bottle in their older years [2].

Prior to my wee one's first birthday, my doctor talked to me about transferring to a sippy cup. She explained that drinking from a bottle causes the milk, formula or juice to collect causing “baby-bottle” tooth decay.

To see what the AAFP recommends, .

The American Academy of Family
Physicians [3] provides five tips to avoid baby-bottle tooth decay:

• Put your child to bed with a bottle of plain water, not milk or juice.
• Stop nursing when your child is asleep or has stopped sucking on the bottle.
• Try not to let your child walk around using a bottle of milk or juice as a pacifier.
• Start to teach your child to drink from a cup at about 6 months of age. Plan to stop using a bottle by 12 to 14 months at the latest.
• Don't dip your child's pacifier in honey or sugar.
