Pigeon Peristaltic Slim Neck Teat is a solution that is supposed to assist each mum with calming down their baby. Pigeon's research conducted on baby's oral devlopment shows that baby suckles breastmilk by moving their tongue in a smooth, wave-like motion. This is called 'Peristaltic motion' and is the natural way a baby feeds. Pigeon teats have been designed to mimic and promote this natural sucking action. Pigeon teats will reduce nipple confusion between breast and bottle. Suitable for slim necked bottles.
