Natural milk flow like breastfeeding \ \ The Philips Avent Natural Response bottle has a nipple that works like the mother's breast, giving your baby a flow rate similar to natural breastfeeding. Milk is released only when your baby drinks, helping to reduce feeding problems and ensuring calm, natural movements during feeding. \ \ \ Wide & flexible nipple for easy latching \ \ The soft silicone nipple is shaped to mimic a woman's breast, allowing your baby to latch on correctly and feel secure. The natural feel enhances the transition from breastfeeding to bottle, without altering your baby's experience. \ \ \ Ergonomic & lightweight design for little hands \ \ The bottle is designed to be easy to hold from any angle. It is comfortable for both parent and baby's little hands, making feeding easy at every stage. \ \ \ airfree vent to reduce colic \ \ the special airfree valve prevents air from entering the baby when feeding in an upright position, helping to reduce discomfort, bloating and colic. Ensures calmer and more comfortable feeding moments. \ \ \ choosing the right flow rate \ \ each baby has their own growth and feeding rates. Thanks to the variety of natural response nipples, it is easy to find the flow that suits your baby. For newborns who need an even slower flow, the first flow nipple may be ideal. \ \ \ anti-leak design \ \ the nipple hole only allows milk to come out when the baby drinks. This prevents milk loss, both at home and when traveling. \ \ \ compatibility with the entire philips avent range \ \ the bottle is fully compatible with avent accessories (breast pumps, nipples, cups), offering flexibility and ease in combining products according to your needs. \ \ \ bpa-free safety & hygiene \ \ natural response nipples and bottles are made of bpa-free materials, for absolute safety at every meal. \ \ \ smooth transition like breastfeeding \ \ because natural response bottles are not free-flowing, your baby may need a little adjustment. this is natural and resembles the breastfeeding process, offering a smoother feeding experience. \ \ \ technical features \ \ \ nipple: silicone, bpa free \ bottle: bpa free \ \ \ \ \ functions \ \ \ natural grip \ soft & flexible nipple \ no-drip design \ airfree anti-colic vent \ \ \ \ \ includes \ \ \ 1 natural response bottle 260ml \ 1 slow flow nipple (3-6m) \ 1 airfree vent \ \
