Aside from transitioning from the breast to a bottle the stomach discomfort that could arise can be alarming for parents. Bottle-feeding tends to increase instances of spit-ups gas and reflux. It doesn’t have to be this way. Moms who are slowly weaning their babies from the breast to a bottle need not worry. As long as you choose the right baby feeding bottle everything should come up roses. Make milk bottle-feeding painless and worry-free with the Baby Blendy Baby Bottle! Babies require extra special care and attention. That’s why we designed a baby bottle that pays attention to their specific needs. Our bottle has a built-in bottom vent that separates air from milk. This way fewer air bubbles make it to your little one’s tummy eliminating possibilities of tummy ache and milk-spitting. The silicone nipple that comes with the bottle is shaped and molded to replicate the human breast. We aim to make it easier for your newborn to transition to bottle-feeding and to latch and suck on the nipple effortlessly. Lengthy feeding times can be a pain to mom and dad. Babies who are learning to hold their bottles on their own could easily tire as well so we made the bottle extra lightweight. The unique shape also makes it easier to grip when shaking or feeding.
