One of the safest and most hygienic dummies on the market.Available in small(0-6 months) and large(6 months +) Which shape is better for my baby? Round Shape - Tends to work better for breastfed babies because the tongue is positioned under the nipple as it is during breastfeeding, which helps prevent nipple confusion. About 80% of babies tend to move soothers around in their mouths, so the position of the round soother can never end up around the wrong way. Because the tongue’s position never changes, midwives usually recommend starting babies on rounded soothers. Natural Rubber Soothers round model is available in small (0-3 months), medium (3-6 months) and large (6 months+). Orthodontic Shape - With the orthodontic shape, the tip of the nipple is slanted to encourage tongue movement against it (as opposed to under it). The tongue’s pressure is directed towards the tip. This shape is ideal for babies who are already accustomed to the orthodontic shape. The Natural Rubber Soother Ortho shape is available in small (0-6 months) and large (6 months+).
