Philips Avent My Natural Starter Cup - Stage: 4-6 Months
The Philips Avent My Natural Starter Cup is designed for the earliest introduction - a bridge between bottle and cup for babies as young as 4 months. The soft silicone spout closely resembles an Avent bottle nipple, which reduces rejection from babies already using Avent bottles. The flow rate is very slow and gentle, appropriate for babies who haven't developed cup suction coordination yet.

Our picks up close
Philips Avent My Natural Starter Cup - Stage: 4-6 Months
The Philips Avent My Natural Starter Cup is designed for the earliest introduction - a bridge between bottle and cup for babies as young as 4 months. The soft silicone spout closely resembles an Avent bottle nipple, which reduces rejection from babies already using Avent bottles. The flow rate is very slow and gentle, appropriate for babies who haven't developed cup suction coordination yet.
Where it shines
- Soft spout mirrors Avent bottle nipple - familiar feel reduces rejection
- Very slow flow rate appropriate for youngest beginners
- Compatible within the Avent ecosystem for brand-loyal families
Where it falls short
- No handles limits independent use at this early stage
- Best within the Avent brand - less benefit if you use different bottles
NUK FC 5oz Learner Cup - Stage: 6-9 Months
The NUK FC 5oz Learner Cup is a step-up cup for babies who have had some soft-spout exposure and are ready for slightly more demand. The orthodontic spout is NUK's signature flat-top shape, designed to support natural oral development. The spout requires slightly more active suction than the softest first cups, making it ideal for the 6-9 month stage when babies are building strength and coordination.
Where it shines
- Orthodontic spout shape supports healthy oral development
- T-shaped handles are among the easiest for 6-9 month grips
- Graduated difficulty from ultra-soft cups - good stage progression
Where it falls short
- Harder spout than first-stage cups - may frustrate youngest 6-month-olds
- NUK orthodontic spout doesn't appeal to all babies
Boon Pulp Silicone Feeder & Cup - Stage: 6-10 Months
The Boon Pulp Silicone Feeder & Cup occupies a unique role: it's a mesh/silicone feeder that doubles as a cup introduction tool. The silicone pouch can hold soft foods, frozen breast milk, or water, letting baby self-feed liquids and purees simultaneously. This makes it a natural fit for families doing baby-led weaning or anyone bridging the gap between spoon feeding and independent drinking.
Where it shines
- Bridges solids and liquids - ideal for BLW or combo-feeding families
- Silicone is soft, safe, and durable for mouthing
- Develops cup hand-to-mouth coordination in a safe, contained format
Where it falls short
- Not a standalone cup - more of a bridge and supplemental tool
- Mesh/silicone feeder portion requires careful cleaning to prevent mold
Munchkin Miracle 360 Degree Cup - Stage: 9-18 Months
By 9-12 months, many babies are ready for a cup that looks and functions more like a real cup - and the Munchkin Miracle 360 Degree Cup is the benchmark product for this stage. The 360-degree rim means baby can drink from any point around the edge, exactly like a real cup, without the cup needing to tip or baby needing to find a spout.
Where it shines
- 360-degree rim mimics open cup drinking - best for oral development
- No suction valve - baby drinks freely without frustration
- Spillproof when not actively drinking - practical for mealtimes
Where it falls short
- 360-degree rim can be confusing for babies under 9 months
- Valve assembly requires careful disassembly to clean fully
Joovy Boob PPSU Bottle-to-Cup - Stage: 8-15 Months
The Joovy Boob PPSU is a clever product for parents who want a direct bottle-to-cup transition without buying a completely new product. The Boob system uses interchangeable lids - you start with the nipple lid for bottle feeding, then swap to the training spout lid or straw lid as baby progresses. PPSU is a premium, hospital-grade plastic that's BPA-free, heat-resistant, and highly durable.
Where it shines
- Interchangeable lids allow bottle-to-cup progression without new purchase
- PPSU is premium, BPA-free, and highly heat-resistant
- Familiar body shape reduces cup rejection during transition
Where it falls short
- Requires investment in multiple lid types for full benefit
- Less widely available than mainstream brands at retail
Before you buy
Match the cup to the stage
- the biggest mistake parents make is buying a cup designed for a different developmental stage. A 360-degree cup that requires mature suction understanding will frustrate a 5-month-old. Match the flow resistance and spout type to where your baby actually is.
Soft to firm spout progression
- start ultra-soft (4-6 months), move to orthodontic spout (6-9 months), progress to 360-degree rim or straw (9-18 months). This mirrors the development of oral motor strength and coordination.
BPA-free materials
- all five products above are BPA-free. Also check for BPS and phthalate-free claims, especially for youngest babies whose immune systems are still developing.
Easy disassembly for cleaning
- cups with complex valves need full disassembly after every use to prevent mold. Choose designs with as few parts as possible if thorough daily cleaning isn't realistic.
Size appropriate to the stage
- 2-4oz for early introduction (wastes less), 5-8oz as drinking ability improves, 10oz+ only once real consumption begins.
The wrap-up
If you're starting from scratch and want one cup per stage: begin with the **Philips Avent My Natural Starter Cup** at 4-6 months, progress to the **NUK FC Learner Cup** at 6-9 months, and transition to the **Munchkin Miracle 360** from 9 months onward.

Quick answers
Most pediatricians recommend introducing a cup around 6 months, when babies typically start solids. However, you can offer a soft-spout or open cup as early as 4 months for exploration. The priority at this stage is building familiarity and oral motor skills, not actual hydration - breast milk or formula remains primary until 12 months.
The typical progression moves from bottle (newborn-6 months) → soft-spout starter cup (4-8 months) → open cup or soft straw cup (6-12 months) → 360-degree training cup or straw cup (9-15 months) → regular open cup with handles (12-18 months). Every baby moves at their own pace; the stages overlap and there's no hard schedule to follow.
The American Academy of Pediatrics recommends transitioning away from sippy cups by around 18-24 months, moving toward open cups. Extended sippy cup use has been linked to dental issues and delayed oral motor development. Introducing open cup practice early - even as a side activity from 6 months - makes this transition much easier.
