If your child still uses a bottle past their first birthday, you’re not alone — many parents feel unsure about when and how to transition from bottle to cup. This change is more than a developmental milestone; it also plays a big role in your child’s dental health.

At Molar Opposites Kids Dentistry in Sedona, AZ, we help parents navigate this transition every week. The good news? With a plan (and a little patience), you can make this shift smooth and positive.

When Should You Start the Transition?

Most pediatric dentists — including us — recommend:

• Introduce a training cup at 6 months (when they start solids)

• Begin reducing bottle use at 12 months

• Fully transition away from bottles by 18 months

Why? Because prolonged bottle use increases a child’s exposure to sugars (even natural sugars in milk), which can lead to baby bottle tooth decay — cavities that often appear on the top front teeth.

Baby Bottle Tooth Decay: Why It Happens

Letting a child fall asleep with a bottle or sip on milk throughout the day causes liquid to pool around the teeth, feeding bacteria that create acids and lead to decay.

Common cavity culprits:

• Milk

• Juice

• Formula

• Sweetened drinks

Water is the only liquid that’s safe for extended sipping or bedtime.

How to Transition — Simple Step-by-Step Plan

Here’s the same plan we share with parents at our kids dentistry office in Sedona, AZ:

Step 1: Introduce a Training (or Sippy) Cup

Start as early as 6 months — offer small sips of water with meals.Make it fun: let them choose a color or a cup with a favorite character.

Step 2: Drop the Daytime Bottles First

Replace one bottle feeding every few days with:

• Milk in a cup

• A snack

• A cuddle session

Most toddlers adjust quickly once they realize cups are part of the routine.

Step 3: Save the Bedtime Bottle for Last

This one’s emotional — for both parent and toddler.What can you offer instead?

• A bedtime story

• Extra snuggle time

• Water in a cup (if they really want something)

Do not offer milk or juice at bedtime, even in a cup.

Step 4: Brush Teeth After the Last Milk of the Day

Even a small amount of milk left on teeth overnight can trigger cavities.

What If My Child Refuses the Cup?

Totally normal. Kids love routine.

Try these dentist-approved hacks:

• Offer a straw cup (many kids find it more exciting).

• Make cup use part of "big kid" language: “Cups are for big kids!”

• Reduce the bottle gradually — don’t go cold turkey unless you need to.

If you’ve been trying and nothing works, it may be about comfort, not thirst. Swap that comfort:

• Replace milk with water

• Replace bottle with a comfort object (blanket, stuffed animal)

Should I Switch to Sippy Cups or Go Straight to Open Cups?

Sippy cups are great training tools — they prevent spills and help the transition feel familiar.

But pediatric dentists love open cups and straw cups the most because:

• They promote better oral muscle development

• They reduce prolonged sucking habits

• They support proper speech development

If possible, use sippy cups only temporarily.

What Should My Child Drink?

The simplest rule of kids dentistry:

Daily liquid goals (general guidance):

Milk is healthy — just offer it with meals, not as a constant sipper.
