Quick Answer
Many babies can practice with a cup around 6 months and build straw skills in the second half of the first year, with lots of spills and supervision. AAP guidance recommends moving away from the bottle by about 12 months. CDC infant nutrition guidance supports healthy drinks and meal routines as solids expand. Health Canada guidance keeps breast milk or formula as the main drink under 12 months. Straw cups are a tool, not a deadline—readiness depends on sitting well, interest, and clinician input.
What Parents Need to Know
Cup learning is messy. Short practice sessions at the high chair teach babies that liquid comes from more than a nipple.
Some infants prefer open cups first; others take to straws after watching caregivers. Either path is fine when amounts stay small and adults stay nearby.
Night bottles are separate from daytime cup practice. AAP guidance links prolonged bottle use with tooth decay and extra calories from drinks.
Evidence-Based Guidance
AAP discontinuing-the-bottle guidance recommends:
- Introducing a training cup around 6 months during supervised meals
- Phasing out the bottle by about 12 months for most children
- Avoiding putting babies to bed with a bottle
- Limiting fruit juice and offering water with meals when age-appropriate
CDC foods-and-drinks-to-encourage guidance highlights:
- Water and plain milk as preferred drinks after the first year for many families
- Limiting sugary drinks that displace nutritious foods
- Building habits that support healthy weight growth
CDC mealtime guidance adds:
- Regular family meals when possible
- Responsive feeding—watch hunger and fullness cues
- Patience with new skills like cup holding and sipping
Health Canada infant feeding guidance notes:
- Breast milk or formula meet fluid needs for young infants
- Complementary foods gradually increase after about 6 months
- Families should consult health professionals when intake drops or allergies are suspected
Practical Steps
- Start with an open cup or small straw cup at the high chair while baby is alert and supported.
- Offer only 1–2 ounces of breast milk, formula, or water for practice—not a full feed at first.
- Demonstrate sipping; some cups need a gentle squeeze at first—follow product safety labels.
- Expect spills; use a bib and avoid carpet time until skills improve.
- Pair cup time with solids per CDC mealtime routines.
- Reduce bottle frequency gradually after 12 months if your clinician agrees, replacing one bottle at a time with cup meals.
- Skip juice unless your pediatric clinician recommends a specific plan.
How MomAI Agent Helps
MomAI Agent on momaiagent.com helps you log cup type, ounces accepted, and bottle transitions beside AAP and CDC feeding charts—so you see whether milk intake stays steady while skills improve. Mom AI Agent links meal notes with SolidStart and DearBaby feeding timelines; it does not diagnose aspiration or pick orthodontic products.
Safety Considerations
- Always supervise drinking; choking can occur if babies walk or lie down with cups.
- Do not put cereal in bottles unless directed by your clinician.
- Clean valves and straws daily to limit mold; replace worn parts.
- Avoid honey in drinks for infants under 12 months.
- Car seat and crib are not cup-practice zones—liquids belong at the table.
When to Contact a Clinician
Contact your pediatric clinician if:
- Baby coughs or chokes consistently with thin liquids
- Weight gain slows after bottle changes
- Refuses all fluids or has fewer wet diapers
- You need help weaning night bottles safely
- Tooth decay or prolonged bottle use beyond 12–15 months worries you
The Bottom Line
Straw cups fit into the wider shift from bottle to cup that AAP, CDC, and Health Canada guidance describe. Practice early with small amounts, supervision, and steady nutrition from breast milk or formula until your care team agrees on bigger changes.

FAQ
Q: Is a straw cup better than a hard-spout sippy cup?
A: AAP bottle and cup guidance focuses on ending prolonged bottle use and limiting sugary drinks rather than endorsing one brand. Many families introduce an open cup first, then a straw cup with water at the table while breast milk or formula remain the main nutrition under 12 months per Health Canada and CDC guidance.
Q: What should I put in a straw cup for a 7-month-old?
A: For infants under 12 months, breast milk or formula stay the primary drinks. CDC and Health Canada guidance discourage routine juice; small sips of water with meals may be appropriate when your pediatric clinician agrees your baby is ready for cup practice.
Q: How can MomAI Agent help with straw cup practice?
A: MomAI Agent on momaiagent.com lets you note cup type, ounces offered, and spills next to AAP and CDC feeding milestones—useful when coordinating with daycare or a partner. Mom AI Agent ties meal notes to SolidStart and DearBaby timelines; it does not choose cup brands or diagnose swallowing problems.
