YOUR QUESTION. A CLEARER NEXT STEP.
My 18–24-month-old can't drink from an open cup yet — is that a concern?
At 18–24 months, still learning to drink from an open cup is usually completely typical — many toddlers are sipping (with spills) within this window and some take a little longer. Worth a developmental or feeding check only if cup-drinking comes with frequent coughing, choking, gagging, liquid through the nose, very little chewing, or wider delays in talking, hand skills or play. This is a reason to assess early, never a diagnosis.

Learning to sip from an open cup is a messy, marvellous milestone — and most toddlers get there on their own timeline.
In short
For an 18-to-24-month-old, still learning the open cup is usually completely typical — many toddlers are sipping (with plenty of spills) somewhere between 18 and 24 months, and some take a little longer. It becomes worth a gentle developmental check only if cup-drinking trouble travels with frequent coughing, choking or gagging on liquids, food or drink coming back through the nose, very little chewing, or wider delays in talking, hand skills or play. This is not a diagnosis — just a calm signal that a clinician's eye may help.
What's typical at 18–24 months
Open-cup drinking is a skill of practice, not a fixed switch. Around this age you can expect:
- Lots of mess — tipping too fast, dribbling and over-filling the mouth are all part of learning lip, jaw and tongue control.
- Mixed methods — many toddlers still use a sippy or straw cup alongside the open cup, and that's fine while they build the skill.
- Steady improvement — with daily chances to try, sipping gets neater over weeks, not days.
Gentle ways to help: offer a small open cup with just a little water at mealtimes, sit alongside and model sipping, and let your child practise in the bath or at the sink where spills don't matter.
When a check is wise
Arrange a developmental or feeding review if you notice:
- Coughing, choking, gagging or watery eyes with liquids, or a wet, gurgly voice after drinking.
- Liquid coming back through the nose, or frequent chest infections.
- Very little chewing, gagging on lumps, or staying only on purées.
- Wider delays — few words, little pointing or response to name, or difficulty using both hands together.
These point to looking sooner rather than waiting, because early support at this age works beautifully.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Seek a check if cup-drinking comes with frequent coughing, choking, gagging on liquids, a wet or gurgly voice after drinking, liquid coming back through the nose, very little chewing or staying only on purées, or wider delays in words, pointing, response to name, or using both hands together.
In everyday life
Offer a small open cup with just a little water at mealtimes and in the bath, sit alongside and model slow sips — let the spills happen where they don't matter, so your toddler can practise lip and jaw control without pressure.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
By what age should my toddler drink from an open cup?
Many toddlers begin sipping from an open cup, with plenty of spills, between 18 and 24 months, and some take a little longer. It's a skill built through daily practice rather than a fixed switch, so messy attempts are completely normal at this age.
Is it bad if my child still uses a sippy or straw cup?
No — using a sippy or straw cup alongside the open cup is fine while your child builds the skill. Offering small amounts of water in an open cup at mealtimes simply gives gentle practice; there's no need to remove other cups abruptly.
When should I be concerned about cup-drinking?
A check is wise if drinking comes with frequent coughing, choking or gagging, a wet gurgly voice afterwards, liquid coming back through the nose, very little chewing, or wider delays in talking, hand use or play. These point to looking sooner rather than waiting.
How can I help my toddler learn the open cup?
Offer a small cup with just a little water, sit alongside and model slow sipping, and let your child practise in the bath or at the sink where spills don't matter. Patience and daily chances work far better than pressure.
