Cubkins 3-in-1 Sensory Silicone Straw TRAINING CUP | See-Through Window | Zero Plastic | 6 Months+
The See-Through Straw Cup: Textured Straw, Silicone Window, Three Stages.
Designed for babies learning to drink on their own, the Cubkins 3-in-1 Sensory Silicone Straw Training Cup pairs a soft textured silicone straw with a transparent silicone window, so you can see how much your baby has had at a glance. Every part — cup, lid, straw and window — is 100% food-grade silicone. For ages 6 months and above.
🥤 Textured Sensory Straw: Soft raised dots near the tip show your baby how far the straw goes in and give gentle feedback to the lips, designed to encourage a lip seal and to discourage biting. A double ring holds the straw in the lid, and a slight cut on one side of its bottom end lets thicker drinks up.
💧 Press for the First Sip: Gently press the little air hole on the lid and the drink rises up the straw, so the very first try brings a sip instead of a chew.
👀 See Inside at a Glance: The transparent silicone window, with moulded markings from 50ml to 200ml beside it, lets you check how much your baby has drunk and whether the cup is clean. Nothing hidden at the base.
🌿 Zero Plastic: 100% food-grade silicone — cup, lid, straw and window. No plastic part anywhere in the cup.
🔄 One Cup, Three Stages: Straw cup with lid from 6 months, open straw cup (lid off, straw in) from 12 months, and open cup (no lid, no straw) from 18 months.
🧼 Simple to Clean, Nothing to Hide Grime: Takes apart into three pieces — cup, lid and straw. No valves, no hidden crevices. Top-rack dishwasher suitable, steriliser suitable and microwave suitable.
FDA food-contact compliant materials. BPA-Free · PVC-Free · Phthalate-Free · Lead-Free. 200ml · 14 cm handle to handle · 8.5 cm tall with the lid · 150 g. For ages 6 months and above. For use under adult supervision. The straw has no valve, so start with a little liquid while your baby learns.
Many sippy cups use a teat-like spout, so your baby sucks much as they would from a bottle. The Cubkins training cup is designed around a different idea: an open, textured silicone straw.
🔸The Textured Silicone Straw
Every detail on the straw is there for a reason. The soft raised dots near the tip show your baby how far the straw goes in, and they give a gentle signal to the lips and tongue, designed to encourage a lip seal as they learn to sip. A double ring on the straw holds it firmly in the lid. The slight cut on one side of the bottom end is deliberate, not a defect: it lets thicker drinks flow up.
🔸Press for the First Sip
When babies first meet a straw, many chew it instead of sipping. With the straw at your baby's lips, gently press the little air hole on the lid and the drink rises up the straw, so there is something to taste on the very first try.
🔸Free-Flow Design (No Valve)
Unlike valved sippy cups that need a hard suck to release liquid, our straw cup has an open, unrestricted flow. Your baby uses their lips to control how much they sip — designed for practising straw drinking during weaning.
🔸3 Stages That Match Your Baby's Growth
- Stage 1 (6 months+): Straw Cup with Lid — Lid and straw on, for learning to drink from a straw during early weaning.
- Stage 2 (12 months+): Open Straw Cup — Lid off, straw in, for sipping with a little more freedom.
- Stage 3 (18 months+): Open Cup — No lid, no straw, for practising sips straight from the cup.
Most silicone cups are fully opaque, so you cannot see inside. You cannot easily check the base for residue or mould, see how much your baby has actually drunk, or confirm the cup is truly clean.
Cubkins adds a transparent silicone window to the side of the cup.
✅ The window is made from the same 100% food-grade silicone as the rest of the cup — no plastic, no glass.
✅ Moulded markings from 50ml to 200ml beside the window let you see how much your baby has had through the day, without opening the cup.
✅ It takes the guesswork out of cleaning. What you can see, you can clean.
This is not a cosmetic feature. It is the feature this cup is built around.
Straight answers about how our cup works, including the questions parents ask us most.
❓ 'Why does the water taste slightly like dish soap?'
Silicone can absorb fragrance from heavily scented dish soaps. The fix is simple: always wash with an unscented dish soap. For a deep refresh, boil the disassembled parts in a water and white vinegar solution (1:1 ratio) for 5 minutes. The taste usually fades after this.
❓ 'Will liquid spill if my baby drops the cup?'
Yes, some liquid can spill if the cup lands sideways or the lid is pressed — this is a deliberate trade-off. The straw has no valve, so your baby controls the flow with their lips instead of sucking against a valve. We recommend starting with a small amount of liquid (50–80ml) to minimise mess during the learning phase.
❓ 'My baby just bites the straw — what do I do?'
Biting is common in the first few days. With the straw at your baby's lips, gently press the little air hole on the lid: the drink rises up the straw, so they taste it straight away. The raised dots on the straw are designed to give tactile feedback as they learn to sip rather than bite. Many babies get the hang of it after a few days of practice. Tip: Try introducing the straw with a small amount of water or expressed breast milk in the first few sessions.
❓ 'Why is there a cut at the bottom of the straw?'
It is deliberate, not a defect. The slight cut on one side of the bottom end lets thicker drinks flow up the straw.
❓ 'How do I know there is no mould inside?'
Our transparent silicone window was designed for this. Unlike fully opaque cups, you can look at the base of the cup at any time. After washing, always leave the disassembled parts to air-dry completely — mould needs moisture, so fully dry parts matter. If you ever spot discolouration, the cup fully disassembles so you can clean every surface directly.
❓ 'Is this price justified for a baby cup?'
A basic plastic cup does one job for one phase. The Cubkins cup is a 3-in-1 training cup designed to grow with your baby from 6 months through 24+ months: straw cup with lid, open straw cup and open cup. Every part is 100% food-grade silicone — zero plastic. And it adds a transparent silicone window, so you can see what your baby has drunk and that the cup is clean.
🧼 HOW TO CLEAN — DAILY ROUTINE
- Step 1: Fully disassemble all parts (cup body, straw, lid).
- Step 2: Wash each part individually with warm water and an unscented dish soap. Use a thin straw brush for the inside of the straw.
- Step 3: Rinse thoroughly under running water. Check the transparent window — you should be able to see it is fully clear and residue-free.
- Step 4: Allow all parts to air-dry completely on a clean drying rack before reassembling. Do not store wet — mould needs moisture to grow.
🔥 DEEP CLEAN (ONCE A WEEK)
Boil all disassembled parts in a 1:1 mix of water and white vinegar for 5 minutes to help remove absorbed odours. The cup is also top-rack dishwasher suitable, steriliser suitable and microwave suitable.
⚠️ Note on Turmeric: Strong spices like Turmeric (Haldi) may cause slight yellow staining. This is normal for silicone and is cosmetic only.
