Introducing a cup too early or in the wrong format mostly means a lot of spilled water, not any real harm — but picking a cup type that matches a baby's actual stage makes the transition from bottle noticeably smoother.

Step 1. Around 6 Months Is the Practical Starting Point, Not a Strict Rule

Most health guidance suggests introducing a cup alongside weaning, around six months, mainly because that's when a baby is developmentally starting to manage sitting, reaching, and coordinated hand-to-mouth movement — the same readiness signals relevant to starting solids. There's no harm in offering a cup slightly earlier for play and practice; actual independent drinking usually comes later regardless.

This is worth treating as "roughly when to start offering," not a deadline — a baby who isn't interested at 6 months isn't behind; readiness varies as much here as with any other feeding milestone.

Step 2. Spouted Cups Are the Easiest First Step From a Bottle Teat

A soft or firm spouted cup, like the Liewood Neil or Trixie cup with handles, most closely resembles a bottle teat's shape, making it the gentlest transition for a baby used to bottle or breast feeding. The spill-proof valve inside controls flow so liquid doesn't pour out freely when tipped.

This is generally the right starting format specifically because it asks the least new mouth-coordination from a baby who's only known a bottle or breast so far — other cup types can come later as skills develop.

Step 3. Straw Cups Build a Genuinely Different, More Advanced Skill

Drinking through a straw requires actively sucking to draw liquid up, a different mechanic from a spouted cup's more passive sipping — it's a skill that typically develops a bit later, often introduced from around 9-12 months. Straw cups are worth introducing once a spouted cup is well established, not as a first cup.

Straw drinking is also considered better for oral development long-term than prolonged spouted-cup use, which is why many parents transition toward straw cups over the following months — not urgent, but worth working toward rather than staying on spouts indefinitely.

Step 4. 360° Rim Cups Teach Real Open-Cup Drinking Without the Mess

A 360° cup, like the Little Dutch Trainer Cup, has a rim that can be sipped from at any point around its edge, with a valve that only releases liquid under gentle suction — genuinely closer to drinking from an open adult cup than either spouted or straw designs, without the spill risk of a truly open cup.

This is the format most directly building toward drinking from a normal cup, worth introducing once a baby has some cup-handling confidence already, as a bridge to open-cup drinking rather than a first-ever cup.

Step 5. Handles Matter More for Grip Confidence Than Cup Type Does

Two-handled cups, common across the Liewood, Trixie and Elodie Details ranges, give a young child a stable double grip that a single-handled or handle-free cup doesn't, which matters more for early independent holding than the specific spout mechanism. A baby confident with a two-handled cup often manages an unhandled one shortly after.

Prioritising handles early on, regardless of spout type, tends to matter more for a baby's actual success at self-drinking than which valve design you pick.

Step 6. Dishwasher-Safe Design Matters More Than It Seems Once You're Doing This Daily

A sippy cup gets used and needs washing multiple times a day, every day, for a long stretch — checking a specific model is genuinely dishwasher-safe (not just "wipeable"), like the Elodie Details and Liewood ranges explicitly state, saves real daily effort compared to hand-washing valve parts repeatedly.

This is a small spec that has an outsized effect on daily hassle — worth checking before buying multiples of a cup that turns out to need careful hand-washing every single use.

FAQ

What age should I introduce a sippy cup?
Around 6 months is the practical starting point, roughly alongside weaning, but it's about developmental readiness rather than a strict age — no harm in starting a little later. See Step 1.

Spouted, straw, or 360° cup — which should I buy first?
Start with a spouted cup, since it's closest to a bottle teat. Introduce a straw cup once that's established (often 9-12 months), and a 360° rim cup as a bridge toward open-cup drinking. See Steps 2-4.

Is straw drinking actually better than a spouted cup long-term?
Many consider it better for oral development over time, which is why most families transition toward straw cups eventually rather than staying on spouted cups indefinitely. See Step 3.

Do handles actually matter, or just the cup design?
Yes — a two-handled cup gives a more stable grip for early independent holding than spout type alone, and tends to build confidence that carries over to unhandled cups. See Step 5.
