Open cup, straw cup, sippy cup: what parents should know

Open cup, straw cup, sippy cup: what parents should know
Cup drinking is not one skill learned in one day. It is a gradual move from bottle dependence toward steadier, self-led drinking.

  1. What each cup means

Cup
Learning Goal
Parent Note
Bottle

Primarily for breast milk or formula feeding, not for cup-drinking practice.
  • AAP recommends transitioning from bottle by 12–18 months to reduce prolonged dependence.
Sippy / spouted training cup
Helps babies transition from bottle to cup with less spilling, and works well for short-term practice.
  • Sippy cups are teaching tools and should not be used long-term; stop using once the child can drink from a regular cup.
Straw cup

Supports straw drinking, two-handed cup holding, and seated water practice, while also being convenient for outings.
  • Straws, valves, and lids should be cleaned regularly and dried thoroughly.
Open cup
Supports lip closure, small-sip control, and hand-mouth coordination.
  • Start with very small amounts of water, hold the cup for your baby, and expect some spills—this is normal.

  1. Readiness signs by age

Age is a guide, but body readiness matters more. Before cup practice, babies should be able to sit with support or sit steadily, have good head control, and have started solids.
  • Around 6 months: keep practicing short and small. This may mean a spouted training cup, a straw cup, or a tiny open-cup sip with adult support.
  • 9-12 months: many babies become more interested in holding the cup, biting the rim or straw, and trying again. Spills are expected. ASHA notes that 6-12 month olds may start drinking from a cup, while biting the cup edge or straw and spilling some liquid.
  • 12-18 months: many children can drink from a sippy cup without help and can drink from an open cup with some spilling; straw drinking may also become steadier.

  1. How to start with small sips

Offer cup practice when your baby is seated, alert, and calm during a meal. Begin with a very small amount of water. Let your baby experience the rim or straw before expecting a real drink.
  • Open cup: add one tiny sip of water, hold the cup with your baby, touch the rim gently to the lower lip, and tilt slowly.
  • Straw cup: let your baby explore the straw first; use a small amount of water. If the cup has a valve, make sure the suction is not too hard.
  • Sippy cup: use it as a short-term bridge, especially for travel or moments when spills need to be limited.
  • One to three minutes is enough. If your baby becomes upset, coughs repeatedly, or refuses, pause and try another time.

 

Start with tiny sips. The goal is practice, not a full drink.

 

  1. Common mistakes

  • Using a sippy cup as a long-term bottle replacement. It can be a bridge, but not the destination.
  • Letting a child walk around with a cup. Spouted and straw cups can easily become all-day sipping habits.
  • Adding too much water at the beginning. With open cup practice, less is calmer.
  • Forgetting the cleaning burden. Straws, valves, and lids need to come apart, wash well, and dry fully.
  • Treating spills as failure. With open cups, spills are part of the lesson.
