What Drinks Go in Sippy Cups?

✅ GOOD:

• Water (unlimited, best choice)
• Milk at mealtimes (15-20 minute sessions)
• Diluted formula (transition period only)

⚠️ OCCASIONAL:

• Diluted fruit juice (1:4 juice:water ratio, maximum 50ml/day)
• Only at mealtimes (not throughout day)
• Better to avoid entirely (unnecessary sugar)

❌ NEVER:

• Undiluted juice (too much sugar = tooth decay)
• Soft drink/cordial (absolutely not for babies/toddlers)
• Honey water (botulism risk under 12 months)
• Sugary drinks all day (ruins developing teeth)

Australian guidelines: Water is best drink for babies/toddlers. Milk at meals only.

Sippy Cups vs Open Cups: The Goal

Remember:

• Sippy cups are transition tools, not permanent
• Goal is open cup drinking (like adults)
• By age 2-3, using regular cups most of the time
• Sippy cups mainly for travel/spill prevention

Timeline:

• 6 months: Start open cup practice (with help)
• 12 months: Independent sippy cup use
• 18 months: Open cup at home, sippy for outings
• 24+ months: Mainly open cups, sippy occasionally

Don’t rush, but don’t delay:

• Every child develops at own pace
• But don’t let sippy cup become “security blanket”
• Encourage progression toward open cups

Q: When should I introduce a sippy cup?

A: Around 6 months when baby sits unassisted. Start with water, not replacing bottle feeds yet.

Sippy cups are developmental tools, not permanent solutions. Choose straw or 360-style for best oral health. Start early (6+ months), transition gradually, and aim for open cup drinking by age 2-3. Most importantly: water in cups throughout the day, milk only at mealtimes. 🥤
