Formula Feeding for Newborns
If your baby was born prematurely, has a medical condition, or is under the care of a neonatal team, your healthcare provider will give you specific feeding guidance. The information on this page is for healthy term newborns only.
Newborns have small stomachs and feed frequently. In the first few weeks, formula-fed babies typically feed 8–12 times in 24 hours [1]. This is normal and does not indicate a problem with the formula or your technique.
How much formula in the first week
Most formula-fed newborns take 1–2 oz (30–60 ml) every 2–3 hours in the first days, and amounts rise over the following weeks [1].
General guide only — individual needs vary: the AAP's average for formula-fed babies is about 2½ oz (75 ml) of formula per pound of body weight per day, and no more than about 32 oz (960 ml) in 24 hours [2]. Your paediatrician or health visitor may advise different volumes based on your baby's specific growth and health.
Reading hunger cues
Responsive feeding — responding to your baby's hunger cues rather than feeding strictly by the clock — is recommended. Early hunger cues include rooting (turning head and opening mouth), hand-to-mouth movements, and increased alertness or restlessness. Crying is a late hunger cue; feeding before your baby reaches the crying stage is generally easier for both of you.
Reading fullness cues
Signs that your baby has had enough include turning the head away from the teat, slowing the pace of sucking, releasing the teat, relaxing the hands (from fists to open), and becoming drowsy. It is important not to pressure your baby to finish the bottle. Overfeeding is a known issue with bottle feeding and responsive feeding helps prevent it.
Feeding frequency
In the first days, most newborns feed every 2–3 hours, including overnight [1]. As your baby grows, feeds become less frequent and larger volumes are taken at each feed. There is no need to enforce a strict schedule in the early weeks — follow your baby's cues.
Formula preparation for a newborn
The CDC recommends preparing each feed with water that has been boiled and allowed to cool for about five minutes, to no less than 70°C [3]. This temperature is important because it kills certain bacteria (including Cronobacter sakazakii) that can occasionally contaminate powdered formula during manufacture.
What to expect
Newborns often seem unsettled, especially in the evenings. This is common in the first few weeks and is not usually related to formula. Cluster feeding — short, frequent feeds over several hours — is normal behaviour and does not mean your baby is not getting enough.
Weight gain is the most reliable indicator of adequate intake. Most newborns lose some weight in the first 3–4 days and then gain steadily [4]. If you have concerns about weight, consult your midwife or health visitor.
Seek same-day medical advice if your newborn: is not gaining weight, shows signs of dehydration (dry mouth, sunken fontanelle, fewer than six heavy wet nappies in 24 hours from day 5 [4]), is lethargic or difficult to rouse, is persistently vomiting, or you are concerned about their intake for any reason.
