Baby Feeding Guide: What New Parents Need to Know

Feeding a new baby can feel surprisingly complicated. You may be wondering how often your baby should feed, how to tell whether they are getting enough milk, whether breastfeeding or formula feeding changes what you need to do, and what happens when solids eventually enter the picture.

The reassuring starting point is that there is no single feeding experience that every family has to follow. In the early months, babies are generally fed breast milk, first infant formula, or a combination of the two. NHS guidance recommends responsive feeding, which means noticing your baby’s feeding cues rather than trying to make every feed fit a rigid timetable.

As your baby grows, feeding changes too. Solid foods are usually introduced from around six months, while breast milk or first infant formula remains an important part of their diet.

This baby feeding guide covers the essentials so you can understand what to expect, what to look out for and where to get support if feeding does not feel quite right.

Feeding your baby in the early months

During the first months, your baby’s nutrition will come from breast milk, first infant formula, or both.

Some parents breastfeed exclusively. Some express milk. Some use formula from the beginning. Others combination feed. Your circumstances, preferences and feeding experience may change over time, and needing support does not mean you are doing anything wrong.

Rather than expecting a newborn to follow a precise schedule, it can be more useful to learn their early feeding cues.

A baby who is ready to feed may become restless, move their head and mouth around, or suck their fingers. Crying can be a later sign of hunger, so noticing earlier cues may make it easier to settle into a feed.

NHS guidance describes feeding according to your baby’s needs as responsive feeding. For breastfeeding families, this means allowing your baby to feed as often and for as long as they want. Bottle feeding can also be responsive, with parents watching the baby’s cues and allowing pauses rather than encouraging them to finish a set amount.

Feeding patterns can vary considerably. Some feeds may be short and others longer. Babies may sometimes want to feed more frequently than they did the day before.

If you are concerned about the amount your baby is taking, their weight, their nappies or a sudden change in feeding, speak to your midwife, health visitor or GP rather than relying on a generic feeding schedule.

Breastfeeding: what new parents should know

Breastfeeding is natural, but that does not mean it always feels straightforward at first. Positioning and attachment can take practice, and getting skilled support early can make a real difference if feeds are painful or you are worried about milk transfer.

According to the NHS, signs that breastfeeding is going well can include being able to see or hear your baby swallowing, rounded cheeks while sucking and your baby appearing calm during feeds. Your baby should also gain weight steadily after the initial weight loss that can happen in the first few days after birth.

Persistent nipple or breast pain is worth discussing with a midwife, health visitor or breastfeeding supporter. Pain should not simply be something you feel you have to tolerate.

If you are wondering whether your baby is getting enough breast milk, avoid judging this by how full your breasts feel or how long a particular feed lasts. Feeding behaviour, weight and other clinical signs provide a more useful overall picture.

You can ask your midwife or health visitor to watch a feed if you are uncertain about positioning, attachment or whether your baby seems to be feeding effectively.

Formula feeding and combination feeding

If you use formula, the NHS advises using first infant formula as your baby’s main formula during the first year. UK infant formulas have to meet nutritional standards, so a more expensive brand is not automatically better for your baby.

Safe preparation matters. Follow the manufacturer’s instructions carefully and use the correct quantities of water and formula powder. Do not add extra powder to make a feed stronger and do not dilute feeds with additional water.

Bottles, teats and other feeding equipment need careful cleaning and sterilising. NHS guidance advises sterilising feeding equipment until your baby is at least 12 months old.

Bottle feeding can still be responsive and close. Hold your baby during the feed, look for signs that they need a pause and allow them to decide when they have had enough. A baby does not need to finish every bottle.

If you are combination feeding, your routine may involve breastfeeding, expressed milk and formula in different proportions. If maintaining or increasing your breast milk supply is important to you, speak to a midwife, health visitor or breastfeeding specialist for individual advice, because introducing formula feeds can affect milk production.

How can you tell if your baby is feeding well?

It is very common to wonder whether a baby is getting enough, particularly when breastfeeding because you cannot see the amount of milk they have taken.

There is no single sign to rely on. Your baby’s feeding behaviour, nappies, alertness and weight gain all contribute to the picture.

For breastfeeding, the NHS lists signs such as rhythmic sucking and swallowing, rounded cheeks during feeds, appearing relaxed and satisfied after most feeds, and steady weight gain after the first few days.

If you are worried, ask a health professional to assess the whole picture rather than trying to solve it by increasing feeds or changing formula on your own.

It is especially worth asking for advice if feeding has suddenly become difficult, your baby repeatedly refuses feeds, feeding seems painful for them, you are worried about their weight or you have concerns about hydration.

Vitamins and baby feeding

Vitamin recommendations are one area where it is useful to follow current NHS guidance rather than general advice online.

The NHS recommends that breastfed babies from birth to one year are given a daily vitamin D supplement containing 8.5 to 10 micrograms. This also applies to babies who are partially breastfed.

Formula is already fortified with vitamins. Babies having 500 ml or more of formula a day do not need an additional vitamin D supplement.

Recommendations change as babies grow, so check the current NHS guidance or ask your health visitor before choosing a supplement. Make sure any vitamin product you use is suitable for your baby’s age and follow the directions provided.

Starting solid foods

Introducing solid foods, sometimes called weaning or complementary feeding, usually begins at around six months.

The NHS recommends looking for three developmental signs together. Your baby should be able to stay in a sitting position and hold their head steady, coordinate their eyes, hands and mouth so they can pick up food and bring it to their mouth, and swallow food rather than pushing it back out.

Waking more often at night, chewing fists or wanting additional milk feeds do not necessarily mean a baby is ready for solids.

When solids begin, milk still matters. Breast milk or first infant formula should remain your baby’s main drink during their first year.

Early meals do not need to be elaborate. The first stage is partly about learning new tastes, textures and eating skills. Some babies take to food quickly, while others need repeated, low-pressure opportunities to become familiar with it.

You can offer different textures as your baby develops the skills to manage them. NHS guidance encourages moving on from smooth purées to mashed, lumpy and finger foods as soon as your baby can cope with them.

Try not to judge progress by how much food disappears from the bowl. Exploring, touching, dropping and tasting food are all part of learning to eat.

Allergens and feeding safely

Foods that can cause allergic reactions can be introduced from around six months alongside other foods. NHS guidance recommends introducing potential allergens one at a time and in small amounts so that you can notice a reaction.

These foods include eggs, peanuts and nuts, gluten, fish, shellfish, soya and cows’ milk. Nuts and peanuts must be prepared in an age-appropriate form, such as crushed or ground, rather than given whole.

If your baby has a diagnosed allergy or eczema, or there is a family history of allergies, eczema, asthma or hay fever, speak to your GP or health visitor before introducing allergenic foods.

Food preparation also needs a little extra care during weaning. Always supervise your baby while they eat and make sure they are sitting safely upright. Foods that are hard, round or otherwise difficult for a baby to manage need to be avoided or prepared appropriately to reduce choking risk.

It is useful for anyone caring for your baby to understand the difference between gagging and choking and to know what to do in a choking emergency. Current NHS and Best Start in Life guidance can help you learn the appropriate safety steps.

A simple approach to feeding without unnecessary pressure

Baby feeding can easily become a source of comparison. One baby may breastfeed frequently, another may settle into bottle feeds differently, and two babies starting solids at the same age may eat very different amounts.

Try to focus on your own baby’s cues and development rather than another family’s routine.

You also do not need every feed or meal to look perfect. Expressed milk, formula, homemade food and convenient options can all have a place depending on your baby’s age and your family’s circumstances.

As solids become established, variety is useful, but it can take time for babies to accept unfamiliar tastes and textures. Rejection on one day does not necessarily mean a food has to disappear from the menu forever.

If feeding is becoming stressful, painful or dominated by worry, support is available. You do not have to wait until there is a serious problem before asking a health visitor, midwife or GP for advice.

When to get professional advice

Contact your midwife, health visitor, GP or another qualified healthcare professional if you are worried about your baby’s feeding, growth or hydration.

Ask for advice if your baby is not feeding as expected, repeatedly refuses feeds, seems unusually sleepy or difficult to wake for feeds, is vomiting repeatedly, appears unwell, or if you are concerned that they are not getting enough milk.

Breastfeeding parents should also seek support for persistent pain, damaged nipples, breast symptoms that concern them or worries about milk supply. A trained breastfeeding supporter can help with positioning and attachment, while a healthcare professional can assess symptoms that may need medical attention.

If you are formula feeding and think your baby may need a different or specialist formula, speak to a health professional rather than switching repeatedly based on symptoms alone.

For weaning, ask your GP or health visitor for individual advice if your baby was born prematurely, has feeding or swallowing difficulties, has eczema or a known allergy, or if you are unsure when or how to introduce particular foods.

If your baby appears seriously unwell, has difficulty breathing, becomes unresponsive, or you think they may be having a severe allergic reaction or choking, seek urgent medical help.
