In support of breastfeeding, Pigeon SofTouchTM is designed to facilitate a natural switch between breast and bottle by allowing the same natural sucking motion as when your baby drinks from the breast. Made more sustainable with 20% ISCC mass balance certified Biomass-PP plastic. Bottle comes with a SS size nipple (Round-Cut) that is ideal for newborns (0+ months) as it has a smaller tip and the softness and elasticity is closer to mother's nipple. Newborns have yet to develop any jaw muscles, thus the nipple is designed to support their sucking ability at this age
