Choosing an open cup for your baby: when, how, and which one

Let's say the honest part first: an open cup for a baby will spill. There is no spill-proof open cup, ours included, and any page that promises one is selling you a sippy cup with better marketing. The spills are small, they are part of the learning, and here is how to keep them manageable.

When to introduce an open cup

Around 6 months, alongside solids. That is earlier than most parents expect, and it is the timing feeding professionals (pediatric feeding therapists and speech-language pathologists) tend to favor. The reasoning: drinking from an open rim uses the same lip, tongue, and jaw coordination as mature swallowing, while a valved sippy spout does the work for your baby and keeps the suckling pattern going. A 6-month-old will not master it quickly. That is fine. The point is practice, not performance, and every baby moves at their own pace. If you have concerns about feeding or swallowing, ask your pediatrician or a feeding therapist.

How to do open cup practice without chaos

  • Pour tiny. An ounce or less of water. A tipped cup with a tiny pour is a wipe, not a mop.
  • Keep it at the table. Open cup practice belongs in the highchair at mealtimes, with you there. Roaming the living room with an open cup is how open cups get their reputation.
  • Help, then hover, then hand it over. Start by holding the cup to your baby's lips, move to guiding their hands on the cup, then let them take it. Expect the cup to be a toy some days.
  • Refill instead of over-pouring. More small pours beat one big one, every time.

What to look for in a first cup

Small enough for baby hands, soft enough for gums, and honest about its size: a huge cup means a huge pour or a cup that is mostly air. Soft silicone will not crack when it hits the floor (it will hit the floor), a stable or weighted base saves some of the accidental knocks, and a translucent body lets your baby see the water coming, which genuinely helps them time the sip. Dishwasher safe, because this is a three-times-a-day tool.

First Cup vs. Training Cup: two stages, two cups

  • The First Cup (2oz) is the starting point: sized honestly at 2oz for practice-size pours, with soft, grippy silicone shaped for hands still learning to grasp and a stable base. Its whole job is more successful sips and a smaller mess on the days it tips.
  • The Silicone Training Cup is the next stage: a weighted base that resists tipping (not prevents, resists), a soft rim gentle on gums and new teeth, and a translucent body so your baby can watch the water move. The tapered shape suits a two-handed grip as drinking gets more independent.

Both are open cup trainers, which means both will spill when fully tipped. That is not a flaw; it is the feedback your baby learns from.

Cup skills by age: a quick roadmap

  • Around 6 months: start open cup practice. Tiny pours, your hands on the cup, sips at the highchair. The First Cup (2oz) is built for exactly this stage, and the weighted Silicone Training Cup works here too with help.
  • 6 to 12 months: add short straw practice alongside open cup sips, still with tiny amounts of water. The 5oz Training Cup with Lid + Straw covers both: lid on for straw sips, lid off for open cup practice at the table.
  • Around 12 months: start phasing out the bottle. Common pediatric guidance is to begin weaning around the first birthday, swapping one bottle feed for a cup feed at a time. Most 1-year-olds can manage the weighted Silicone Training Cup at meals with decreasing help.
  • 18 months and up: independent open cup drinking at meals, with a straw cup for the car and outings. Spills still happen. Fewer of them is the progress.

Every baby moves at their own pace, and these ranges are practice windows, not deadlines. For how open, straw, and sippy cups compare at each stage, see the sippy vs. straw vs. open cup guide.

For the car and the diaper bag

An open cup in a moving stroller is chaos with no lesson in it, and this is exactly where a lid earns its keep. The 5oz Training Cup with Lid + Straw is two cups in one: lid on for spill-resistant straw drinking on the go (spill-resistant, not spill-proof), lid off for supervised open-cup practice back at the table. Straw drinking builds its own useful skills, so outings do not have to be a step backward.

Who should pick something else

If you want a cup a toddler can carry around the house unattended with zero cleanup, an open cup trainer is not that product, and neither is ours. A valved or straw-lid cup fits that job better, with the trade-off that the valve does some of the skill work. For the full picture of how open cups, straw cups, and sippy valves compare, the cup guide lays out the trade-offs honestly.

Frequently asked questions

When should I switch my baby to an open cup?

Start open cup practice around 6 months, alongside solids, rather than waiting to switch all at once. Drinking from an open rim uses the same lip, tongue, and jaw coordination as mature swallowing. A 6-month-old will not master it quickly, and that is fine: the point is practice, not performance.

How do I give my baby an open cup without huge messes?

Pour an ounce or less of water and refill instead of over-pouring, so a tipped cup is a wipe, not a mop. Keep practice in the highchair at mealtimes with you there, start by holding the cup to your baby’s lips, then guide their hands, then let them take it.

Are open cups really better than sippy cups for babies?

Feeding professionals tend to favor open cups because drinking from an open rim uses the same lip, tongue, and jaw coordination as mature swallowing, while a valved sippy spout does the work and keeps the suckling pattern going. Valved and straw-lid cups still fit jobs like unsupervised toddler roaming, with that trade-off.

When should a baby start drinking from an open cup?

Around 6 months, when solids start. Offer a small open cup with an ounce or less of water at the highchair, with your hands on the cup at first. Mastery takes months and that is expected; regular short practice is what builds the skill.

What cup should a 1 year old use?

By 12 months most babies can handle an open cup at meals with decreasing help, and common pediatric guidance is to start phasing out the bottle around the first birthday. A weighted open cup like the Silicone Training Cup works at the table, and a straw cup like the 5oz Training Cup with Lid + Straw covers outings.

Which cup should my baby use in the car or stroller?

For the stroller, car, or diaper bag, use a lid: the 5oz Training Cup with Lid + Straw offers spill-resistant straw drinking on the go, then works as an open cup with the lid off at the table. An open cup in a moving stroller is chaos with no lesson in it.
