Feeding a baby changes significantly over the first year of life, starting with breast milk or formula and gradually introducing solid foods around 6 months. The basics are straightforward: newborns eat small amounts very frequently, portions grow as babies do, and solids come in when your baby shows specific signs of readiness. Here’s what each stage looks like in practice.
How Much and How Often Newborns Eat
In the first days of life, a newborn’s stomach is tiny. Formula-fed babies start with just 1 to 2 ounces per feeding, every 2 to 3 hours. That adds up to 8 to 12 feedings in a 24-hour period, including overnight. Breastfed babies follow a similar schedule, though feedings may be slightly more frequent since breast milk digests faster than formula.
Over the first few weeks and months, the gap between feedings stretches out. Most formula-fed babies settle into a pattern of eating every 3 to 4 hours, taking larger volumes at each feeding as their stomachs grow. Breastfed babies typically space out similarly, though some continue to cluster-feed (eating several times close together, then taking a longer break) for months. There’s no single correct schedule. Your baby’s hunger cues are a more reliable guide than any chart.
Reading Your Baby’s Hunger and Fullness Cues
Babies communicate hunger and fullness clearly if you know what to look for. Before 5 months, a hungry baby will put hands to their mouth, turn their head toward your breast or the bottle, pucker or smack their lips, and clench their fists. Crying is actually a late sign of hunger, so try to catch the earlier signals before your baby gets too upset to latch or eat calmly.
A full baby sends equally clear signals: closing their mouth, turning their head away from the breast or bottle, and relaxing their hands. Resist the urge to push a baby to finish a bottle. Letting them stop when they show fullness helps them develop healthy appetite regulation from the start.
Once babies start solids (around 6 months and beyond), the cues shift. A hungry older baby will reach for or point to food, open their mouth eagerly when offered a spoon, and get visibly excited at the sight of a meal. When they’re done, they’ll push food away, close their mouth, or turn their head. These signals are worth respecting at every age.
Vitamin D for Breastfed Babies
All babies under 12 months need 400 IU of vitamin D daily. Breast milk alone doesn’t provide enough, so breastfed babies (and babies getting a mix of breast milk and formula) should receive a vitamin D supplement beginning shortly after birth. It typically comes as liquid drops. Formula-fed babies who drink 32 ounces or more of formula per day don’t need a separate supplement, since formula is already fortified.
When to Introduce Solid Foods
Most babies are ready for solid foods around 6 months, but the exact timing depends on developmental milestones rather than a calendar date. Your baby is ready when they can sit up alone or with support, control their head and neck steadily, open their mouth when offered food, and swallow food rather than pushing it back out with their tongue. Other signs include bringing objects to their mouth, trying to grasp small items, and moving food from the front of the tongue to the back for swallowing.
Solid foods at this stage are a complement to breast milk or formula, not a replacement. Milk remains the primary source of nutrition through the first year, with solids gradually becoming a bigger part of the diet.
Spoon-Feeding vs. Baby-Led Weaning
There are two main approaches to starting solids, and many families end up using a mix of both.
Traditional spoon-feeding means the parent controls the process, offering pureed or mashed foods on a spoon. This makes it easier to track how much your baby actually eats, introduce one food at a time to watch for allergies, and control textures to reduce choking risk. It’s also simpler to prepare, which matters on busy days.
Baby-led weaning skips purees entirely. Instead, you offer soft, finger-sized pieces of food that your baby picks up and feeds themselves. Babies who self-feed tend to eat more closely to their hunger cues, which can help prevent overfeeding. Early exposure to varied textures and flavors may also reduce picky eating later. The trade-off is messier meals and more difficulty knowing exactly how much food your baby consumed. Gagging is also more common as babies learn to manage new textures, though this is a normal protective reflex and usually improves with time.
Neither approach is nutritionally superior. Choose whatever feels right for your family, or combine them: offer purees on a spoon alongside soft finger foods your baby can explore independently.
Introducing Allergenic Foods
Current guidelines have shifted dramatically from older advice that recommended delaying common allergens. Introducing allergenic foods early, around the time you start solids, can actually reduce the risk of food allergies developing.
This is especially important for peanuts. For babies with severe eczema, egg allergy, or both (conditions that raise peanut allergy risk), peanut-containing foods should be introduced as early as 4 to 6 months. This doesn’t mean handing a baby a whole peanut. Age-appropriate forms include thinning smooth peanut butter with breast milk or mixing peanut powder into a puree. For babies with these risk factors, a blood test or skin prick test may be recommended before the first introduction to determine the safest approach.
For other common allergens like eggs, dairy, wheat, soy, tree nuts, fish, and shellfish, introduce them one at a time over several days so you can identify the source if a reaction occurs.
Foods to Avoid in the First Year
Honey is off-limits for babies under 12 months. It can contain spores that cause infant botulism, a serious form of food poisoning. This applies to honey in any form: don’t add it to food, water, formula, or a pacifier.
Choking is the other major safety concern. Avoid small, sticky, or hard foods that are difficult for a baby to chew and swallow. Specific hazards include whole corn kernels, uncut cherry or grape tomatoes, chewy fruit snacks, marshmallows, and chewing gum. The way food is prepared matters as much as the food itself. Grapes should be quartered lengthwise, not just halved. Round, firm foods need to be cut into strips or mashed. Soft textures and appropriate sizes make almost any food safe.
When to Introduce Water
Babies under 6 months get all the hydration they need from breast milk or formula. Around 6 months, when solids begin, you can start offering small sips of water in an open cup, sippy cup, or straw cup. Keep it to 4 to 8 ounces per day between 6 and 12 months. Water at this stage is about practicing drinking skills, not replacing milk feedings. Juice is unnecessary and best avoided in the first year.
