What should I know about the nutritional needs of a 6- to 12-month-old
Know the average growth rates of a 6- to 12-month-old
Understand which minerals and vitamins are needed during the first year of life
Learn what serving size may be appropriate for babies this age
Relative to their size, babies have a much higher need for energy, vitamins, and minerals than adults.14
As you begin the exciting process of starting solid foods, emphasize nutrient-dense foods to support your baby’s healthy growth and development.
Remember this transition to solid foods is in addition to breastmilk or formula consumption. Don’t use food in place of milk but rather as an increasingly important supplement. Your baby is still receiving most of their calories and dietary nutrients from breastmilk and/or infant formula.23
Average weight gain and growth for a 6 to 12 month old
Babies 6-12 months old will gain around 3 to 5 ounces per week.4
Note that breastfed babies tend to gain slightly more weight than formula-fed babies during the first few months of life, but then formula-fed babies tend to gain more weight than breastfed babies in the latter part of the first year.4
By your baby’s first birthday, they will likely weigh about three times their birth weight.4
To accurately gauge weight gain over time, your baby should be weighed on the same scale with the same amount of clothing (or better yet, naked!).

Nutrients important for growth and development between 6 and 12 months
While breastmilk and formula will provide most of your little one’s nutrition and calories until they are close to a year old, offering nutrient-rich foods will help your little one build healthy eating habits for the future.56
There are also a couple of nutrient gaps that may need to be filled starting around 6 months.
The below nutrients are some (but not all!) of the vitamins and minerals that play a role in your baby’s growth and development. Aim to introduce and include some (or all!) of these foods to help provide a varied and nourishing diet.
Remember that your little one may not get every nutrient every day, and that’s okay! Over time and with repeated exposure to all different foods, your little one will get what they need.
Note: Food sources of these nutrients are listed below but may not be in a form appropriate for babies. Make sure to choose foods that are appropriate for your baby’s age and stage of eating, as well as for your baby’s oral motor skill level.7
Iron
Iron is most easily absorbed from red meat, but also found in spinach and other dark green leafy vegetables (Swiss chard, beet, collard greens, Bok Bhoy, kale); beans (lentils, garbanzos, navy, kidney, black, pinto); tofu, and iron-fortified infant cereals.8
When you eat iron-rich plant foods along with foods containing vitamin C, the body absorbs iron much better.9 For example, add a squeeze of lemon to beans or a squeeze of orange to chopped, sautéed leafy greens.
Iron is particularly important for breastfed babies who take in minimal or no formula. This is because breastmilk contains very little iron. The American Academy of Pediatrics recommends an iron supplement for breastfed babies until they are introduced to iron-rich solids at 6 months.10
Chat with your baby’s pediatrician before introducing a supplement. Also, be sure to include plenty of iron-rich foods in your baby’s diet!
Zinc
Foods that contain zinc include beef, lamb, turkey, shrimp, pumpkin and sesame seeds, lentils, garbanzos, spinach, asparagus, quinoa, yogurt, fortified grains, tofu, tahini, and tempeh.11
Vitamin C
Vitamin C is found in many fruits and vegetables and especially high in red bell pepper, orange, grapefruit, kiwifruit, broccoli, strawberries, cantaloupe, and tomato.12

Vitamin A
Food sources of vitamin A include sweet potatoes, carrots, red bell pepper, and other orange- and red-colored fruits and vegetables; dark green leafy vegetables (kale, collards, spinach, chard, beet and mustard greens), as well as yogurt, fortified whole milk, and pickled herring.13

Vitamin D
Food sources of Vitamin D include salmon, fortified whole milk*, fortified milk alternatives*, sardines, egg yolk, canned light tuna, and some fortified whole grain cereals.14
The American Academy of Pediatrics recommends that breastfed infants, and combination-fed (breast milk and formula) infants, should be given 400 IU of vitamin D supplement in liquid form every day beginning soon after birth.1015
Formula-fed infants who are getting at least 32 ounces of formula per day do not need to take vitamin D supplements as formula already contains vitamin D.10
Chat with your child’s pediatrician about supplementation before giving it to your baby.
*Note that babies under 1 year should not be given cow’s milk or plant-based milk alternatives to drink; however, these can be used in small amounts in recipes. Read more here: How Do I Introduce Milk To My Toddler?

How much should I feed my 6 to 12 month old?
From 6 to 9 months of age your baby is still learning the skills needed to eat solid foods, so the amount of solid foods they eat may be quite low.18
At this stage, try feeding your baby 2 to 3 meals a day, and expect the average meal size to be only 2-4 tablespoons each.1719
This amount can vary from child to child and from day to day, so always follow your child’s hunger and fullness cues, and never force your little one to eat.20
By 9 months old, your baby should be ready for 3 full meals and 1 to 2 planned, nutritious snacks each day in addition to breast milk and/or formula.1119
Expect the meal size to increase to approximately ½ to 1 cup per meal (less for snacks). And by their first birthday, your baby will likely be eating 3 full meals and 2 to 3 nutritious snacks each day.11

Tips for feeding your 6- to 12-month-old
Offer a variety of healthy foods
Goal: Offer a wide selection of fruits, vegetables, whole grains, beans, fish, dairy, and meat throughout the week.
It can feel daunting to make sure your child is taking in every single vitamin and mineral needed for development if you are focused on a single day. Instead, look to balance their diet over an entire week.21

Focus on high quality snacks
Goal: Use snack time to incorporate a wide variety of vegetables, fruits, whole grains, nuts/seeds (or nut butters and ground seeds), and dairy; and even lean meat, poultry, and seafood.21
Your little one’s tummy is small so they can’t eat too much at a time. Because of this, snacks end up being an important way for your child to get more of the nutrition they need.
Rather than having the mindset that snacks are an invitation to eat junk food, teach them to ‘eat the rainbow’— offering fruits and vegetables in all colors. Provide a combination of protein, whole grains, and produce.
Many processed snacks have added salt and sugar, which babies do not need. In fact, the 2020-2025 Dietary Guidelines for Americans recommends no added sugar at all before the age of 2 years.23
When choosing convenience foods, look for no added salt or sugar on the ingredient list.

Follow your baby’s hunger and fullness cues
Goal: Offer food when your little one indicates they are hungry and stop feeding them if they seem full or no longer interested in eating.
Following your baby’s hunger and fullness cues is called “responsive feeding.” This practice helps your child develop healthy eating habits for the future.20
It also allows them to learn to listen to their own hunger and fullness cues and self-regulate how much they eat, only eating as much as their body needs each day.424
