NUK
Signature Baby Dummy
7.5/10 overall£5.49 (2 pack)
NUK's heart-shaped, anatomically curved silicone dummy, modelled on the shape of a breastfeeding nipple.
NUK's Signature dummy uses the brand's long-running heart-shaped teat, which flattens slightly on the tongue side rather than being fully symmetrical like the MAM or Tommee Tippee designs — NUK's pitch is that this anatomical curve mimics a mother's nipple shape more closely during breastfeeding, supporting healthy oral development. It's one of the cheapest options here, regularly available at UK supermarkets for close to a fiver, and comes with a plastic carry case that's microwave-safe for sterilising.
Against BIBS, which makes a similar breastfeeding-shape claim using round latex, NUK's version is silicone and roughly half the price, making it a lower-risk way to test whether an anatomical (rather than symmetrical orthodontic) teat suits your baby before spending more on BIBS. Against MAM, the trade-off is largely about buying preference — the anatomical shape only fits one way into the mouth, unlike MAM's symmetrical design, which can mean a bit more fumbling in the early days.
This is a sensible budget pick for parents wanting to try the anatomical/nipple-shaped style without committing to BIBS prices, and NUK's silicone holds up about as well as MAM's over a few months of sterilising. The one real limitation is that because the teat isn't symmetrical, it has to go in the right way round, which matters more in the newborn stage when everyone is tired and reaching for a dummy in the dark.
What we liked
- Cheapest of the five, regularly near £5 in UK supermarkets
- Anatomical heart-shaped teat is a lower-cost way to try the breastfeeding-shape style
- Microwave-safe carry case included for sterilising on the go
Where it falls short
- Not symmetrical, so it has to go in the right way round
- Shape and colour range is less distinctive than MAM or BIBS
- Some babies who prefer a fully rounded latex teat (BIBS-style) still won't settle with this shape

How we scored it
Baby Acceptance
How readily babies typically take to the teat shape and stay settled with it in, based on shape, weight and how it sits against the face.
Durability
How well the dummy holds up to repeated sterilising, biting and daily wear over the months a baby uses one size.
Value for Money
Cost per dummy set against pack size, features (case, glow-in-the-dark, ventilation) and how often families end up replacing them.
Lowest price per dummy of the five, with a sterilising case included.
