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

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.

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.
