Asda has recalled some of its dummies over a choking risk which emerged when one device came apart in a baby's mouth.
The supermarket giant has identified a fault with the product and asked parents to return packs of the Little Angels Cherry Soother.
The fault is understood to affect only a small proportion of the blue and pink dummies purchased since October.
Customers have been asked to either dispose of the products or return them to an Asda store as a "precaution".
In a notice to customers, the supermarket said: "They have been withdrawn from sale and are being recalled from sale due to the possible risk of choking following one customer complaint that the outer casing became detached from the main soother."
The baby was apparently unhurt.
An Asda spokesman said: "When it comes to baby products, we don't take any chances, which is why even though there has only been one complaint, we chose to recall the product.
"If customers have purchased an Asda Little Angels Cherry Soother two-pack, please dispose of it or take it back to your local Asda for a full refund, no receipt is necessary.
"We'd like to apologise for any inconvenience caused."
No other Asda Little Angels soothers or dummies are said to have been affected.
