Make feeding time calm again with the CalmiFlow™ Air Balance Bottle Duo.
Designed for newborns and beyond, these advanced anti-colic bottles feature a patented Air Balance vent system that reduces air ingestion, helping to prevent colic, wind, and reflux. The breast-like, soft silicone teat mimics natural latch and flow, making it easier to switch between breast and bottle — perfect for combination feeding.
The wide-neck, ergonomic shape gives you a steady grip during 3am feeds, while the clear ml/oz markings help you track every feed with confidence. Made from premium BPA-free PPSU, the bottles are heat-resistant, shatterproof, and won’t absorb odours or stains from formula and milk.
Included in the duo: one 160ml for newborns and one 240ml for growing appetites. Both are dishwasher-safe, steriliser-friendly, and compatible with most breast pumps.
From midnight feeds to nursery days, CalmiFlow™ delivers a happier tummy, longer sleep, and less stress for UK parents.
