Difrax's Smart S•Bottle
Reduces Colic/Upset Tummy and Even Ensures A Healthier Feeding Position for the Parent. This smart bottle can be used from birth and is ideal for combining breastfeeding and bottle-feeding. The unique S∙shape means that the bottle nipple is always full of milk and without air. Thanks to the valve in the base, your baby swallows less air and so has less trouble with burping, vomiting, colic and earache. The valve prevents a vacuum being created when baby sucks and ensures a constant flow of milk.
