Different children — different dummies
Children are different and a child's preference in dummies varies from child to child. In 'Filter products' you can sort the teats by e.g. manufacturer, shape and material so that you only see dummies that are relevant to your particular child.
If you have any doubts about the type of dummy your child is already using, or if you want to know more about the different options, then we recommend you read our blog post on the characteristics of different dummies.
