Dummies come in many different sizes but most brands will have a similar size range.  

As a general rule, the following applies: 

Size 1 = 0+ / 0-6 months

Size 2 = 6+ / 6-36 months

Size 3 = 18+ / 18-36 months

Size 1 – the perfect size for newborns/babies

Size 2 – generally the most popular size and the one which many hospitals and nurses will recommend 

Size 3 – for older children. The dummy is often quite big and is significantly larger than the other two sizes. Be wary of starting with this size too soon as it can require some getting used to. 

Please note that the sizes are a guide only. They can vary from brand to brand. Find more information about sizes under each product description on our online shop. 

Why are there so many different sizes?

There is not a standard for dummy sizes which is why sizes can vary so much between brands. The size listed should be considered as a guidance only.
