From first sips to confident big-kid mealtimes, the cup transition is more than just swapping bottles. It’s one of those quiet milestones that happens gradually — and sometimes a little messily.
If you’re wondering when to transition from bottle to cup, you’re not alone. Many parents begin introducing a cup around 6 months when solids start, with a gradual move away from bottles between 12–18 months. But every child develops at their own pace.
The goal isn’t perfection. It’s practice.
Small, steady opportunities to sip from a cup help build oral strength, coordination, and independence — one meal at a time.
Start Small: Open-Cup Practice

It might feel surprising, but open cups are often a great place to begin.
A small Mini Training Cup makes early practice feel manageable:
-
The 2 oz size feels comfortable for little hands
-
A weighted base helps build control
-
Less liquid means fewer big spills
Yes, there may be dribbles at first. That’s normal. Learning to sip is a skill — and like any new skill, it takes practice.
Open-cup drinking encourages natural tongue movement and controlled sipping right from the start.
Straw Cup or 360 Cup — What’s Best?
As coordination improves, many families introduce either a straw cup or a 360 trainer cup. Both can support independence — it just depends on what works best for your child.
Straw Cups

Straw drinking helps encourage lip closure and tongue movement while building oral strength.
Our Silicone Straw Cup features a curved straw designed with developmental experts to support healthy jaw positioning and comfortable sipping. It’s often a natural next step for babies learning to move beyond bottles.
360 Cups

A 360 Training Cup offers a spill-minimizing 360° drinking edge, allowing children to sip from any side.
It gives toddlers a sense of independence while still helping manage the mess that can come with learning.
Both styles can also be used without lids as open cups — extending their use as skills grow.
Why We Avoid Valves and Fully “Spill-Proof” Designs
If you’ve ever searched for the best sippy cup for transitioning from bottle, you’ve probably seen a lot of “100% spill-proof” promises.
While that sounds appealing (especially during busy mornings), many of those cups rely on internal valves that require strong suction to release liquid. That suction can feel a lot like bottle feeding.
During the bottle-to-cup transition, the goal is to help children learn controlled sipping — not continue a sucking pattern.
Cups without internal valves allow liquid to flow more naturally. That supports:
-
Controlled sipping instead of sucking
-
Natural lip closure
-
Better tongue movement
-
Stronger oral coordination
Will there be a few drips while they’re learning? Probably.
But those small spills are part of the process. They’re signs that skills are developing.
We believe building confidence matters more than eliminating every drop.
The Big-Kid Step

As toddlers grow more confident, many families transition to stainless steel or glass cups in 8 oz or 12 oz sizes.
These cups feel more “grown up” while still being thoughtfully sized for smaller hands.
Our 3-in-1 Stainless Steel Cup is designed to grow with your child — offering multiple ways to use it as skills develop and independence increases.
For families who prefer glass, our Glass Cups Designed for Little Hands provide a clear, durable option sized just right for small hands.
There’s no rush. Some children move quickly between stages. Others take their time. Both are completely normal.
Different Tools. Same Goal.
Some kids prefer straws.
Some adapt quickly to open cups.
Some rotate between styles for months.
Every path looks a little different.
The goal isn’t speed — it’s confidence.
Growing independence, one sip at a time.
