introducing a bottle at 6 months or older can be tricky with many babies refusing generic bottles. minbie bottles are different as the nipple allows babies to feed with the same latch and feeding motion used for breastfeeding and feature our anti-reflux and anti-colic functionality for optimal bottle-feeding comfort. this 6 months+ bundle contains both the paced and the fast flow rate nipples helping you match the right nipple to your baby’s natural feeding pace as they grow.
