It looks like a simple product with one job. It isn't — get the shape, stage or material wrong and a baby will reliably refuse a dummy that looks nearly identical to the one they liked. Here's what each variable actually controls.

Step 1. Size Stages Exist Because a Baby's Mouth Actually Changes Shape

Dummies are sold in age-banded sizes — typically 0-6 months, 6-18 months, and beyond — because the nipple length and overall size are built to match a baby's actual mouth and jaw development at each stage, not just a rough size guess. The MAM ranges make this explicit with separate 0-2m, 0-6m and 0-12m sets rather than one universal size.

Using an outgrown size isn't dangerous so much as ineffective — it stops sitting comfortably and a baby will often reject it, which is frequently mistaken for "not liking dummies" when it's really just the wrong size stage.

Step 2. Latex and Silicone Are Both Safe — the Difference Is Feel and Durability

Latex dummies, common across the BIBS and FRIGG ranges, are softer and more flexible, closer in feel to a nipple, but degrade faster with use and need more frequent replacement. Silicone dummies, like the BIBS Infinity range, are firmer, more durable, and don't discolour or perish the way latex can over months of use.

Neither material is safer than the other — this is a genuine preference and durability trade-off, and it's common for a baby to simply prefer the feel of one over the other regardless of which one a parent expected them to like.

Step 3. Symmetrical vs Orthodontic Shape Is a Real Design Difference, Not Styling

A symmetrical (round) dummy, like the BIBS Colour range, can be inserted either way round, while an orthodontic or anatomical shape, like the BIBS Colour Anatomical, is designed to sit a specific way to reduce pressure on developing teeth and gums. Both are safe for regular use; the anatomical shape is specifically designed with long-term oral development in mind.

This is worth considering if dummy use is likely to continue past the first year, since the shape difference matters more the longer and more frequently a dummy is used.

Step 4. A Dummy Clip Solves a Real Daily Problem, Not Just a Styling One

A dummy dropped on the floor, in a pushchair, or out of a car seat is a genuine daily occurrence — a dummy clip, like the Avery Row Pacifier Holder or Loulou Lollipop Pacifier Clip Teething Set, keeps it attached to clothing so it isn't constantly retrieved, washed, or lost. This is a small accessory that solves a disproportionately common frustration.

Worth having from day one rather than after the first few lost dummies make the case for it — the clip itself has no downside and the problem it solves is near-universal.

Step 5. Night-Specific Dummies Use Glow Features for a Genuine Practical Reason

Night dummies, like the Tommee Tippee Night Glow range, include a glow-in-the-dark or UV-charged element specifically so they can be found in a dark room without turning on a light and fully waking a baby (or a parent). This is a real functional difference from a standard daytime dummy, not a cosmetic variant.

Worth having a couple specifically for night use if dummy loss in the dark is a recurring problem — the glow feature earns its keep specifically at 3am, less so during the day.

Step 6. A Steriliser-Compatible Design Matters More in the Early Months

In the newborn stage, dummies typically need regular sterilising alongside bottles — checking a dummy is dishwasher- or steriliser-safe (most modern silicone and latex dummies are) avoids a separate hand-washing routine on top of everything else. This matters less once a baby is older and immune systems are more established, but it's worth checking specifically for newborn-stage dummies.

A dummy that needs special hand-washing care is a genuine daily hassle in the newborn months specifically — checking this before buying multiples avoids discovering it the hard way.

FAQ

Does dummy material (latex vs silicone) matter for safety?
No — both are safe when age-appropriate and not visibly worn. The difference is feel (latex is softer) and durability (silicone lasts longer), and many babies have a genuine preference for one over the other. See Step 2.

Why does my baby keep refusing a dummy that used to work?
The most common cause is an outgrown size stage — dummies are banded by age because mouth shape changes, and an outgrown dummy often just stops sitting comfortably rather than being rejected for any other reason. See Step 1.

Is an orthodontic (anatomical) shape actually better than a round one?
Both are safe; the anatomical shape is specifically designed to reduce pressure on developing teeth and gums, which matters more the longer dummy use continues. See Step 3.

Do I need a dummy clip?
Not essential, but genuinely useful — a dropped, lost or floor-contaminated dummy is a near-daily occurrence, and a clip solves this from day one rather than after repeated frustration. See Step 4.
