Infant

In the first days, most newborns take only about 1 to 2 oz (30-60 ml) per feed, building to roughly 2 to 3 oz by the first few weeks. A general guide is about 2.5 oz per pound of body weight over a full day, but every baby is different, so follow your baby's hunger and fullness cues rather than a fixed number. The BuubiBottle Mini (5 oz) suits these smaller early feeds, and its clear scale lets you measure exactly what your newborn takes.

Newborns typically feed 8 to 12 times in 24 hours, roughly every 2 to 3 hours, including overnight. As your baby grows the gaps stretch out, often to every 3 to 4 hours by around 2 months. Watch for early hunger cues like rooting, lip-smacking, or hands to mouth instead of waiting for crying, and warm the next feed quickly with the BuubiBottle Smart Portable Milk Warmer for those frequent day-and-night feeds.

For the small 1 to 3 oz feeds of the first weeks, the BuubiBottle Mini (5 oz) is the easy starting size, leaving room to grow without overwhelming a tiny tummy. As intake climbs toward 4 to 6 oz per feed over the first months, many parents move up to the BuubiBottle Max (8 oz). Both are made from Grilamid TR 90 Swiss polyamide and are EA Free, so you can size up on the same trusted material.

Start a newborn on the slowest flow so milk releases at a gentle, paced rate they can control, which helps them feed calmly and pause to breathe. RealFeel nipples are IBCLC-recommended and come in Slow, Medium, Fast, and Flex, so begin with Slow and only step up later as your baby's feeding gets stronger and faster. A slow flow is also helpful if your newborn moves between breast and bottle.

Yes, a newborn can take more than they need, often showing up as frequent large spit-ups, extra gassiness, or fussiness right after a feed. Fullness cues include slowing or stopping sucking, turning away from the bottle, and relaxed open hands, so let your baby stop rather than pressing them to finish. Using a slow-flow RealFeel nipple and pausing to burp helps your newborn feed at their own pace and swallow less air.
