child’s immune system

Your child’s immune system is their body’s natural defense against germs. A strong immune system keeps them healthy and helps fight off harmful bacteria and viruses. You can support your child’s immune system by offering nutritious foods, water throughout the day, and making sure they get plenty of sleep and exercise.

Here are a few WIC-approved foods that can help keep your child’s immune system strong, plus simple recipes to try at home!

Lentils

Lentils are a great plant-based protein packed with zinc, iron, and Vitamin B6. These nutrients help the body make white blood cells, which help fight infections. One cup of lentils provides 37% of the daily iron, 17% of the daily zinc, and 18% of the daily Vitamin B6 your child needs.

Don’t Forget Water!

Staying hydrated is key to keeping your child’s immune system working properly. Water helps move infection-fighting cells through the body. Aim to offer water throughout the day to keep your child hydrated. For a fun and flavorful twist, add slices of fruit like lemon, orange, or cucumber to water!

Tips

Mom new born home

Breast milk and formula feeding:

Around 2-3 weeks, 6 weeks, 3 months, and 6 months of age, babies may experience a growth spurt when they feed more often.

As they grow babies can hold more milk, so feedings may become further apart and take less time.

To prevent choking, always hold your baby when feeding. Never prop up a bottle to feed.

Start offering whole milk when your baby is one year old.

The American Academy of Pediatrics recommends exclusive breastfeeding for the first six months and that breastfeeding continue for at least 12 months and beyond.

feeding solid foods

Feeding solid foods:

Wait to offer solid foods until your baby:

To prevent choking, always hold your baby when feeding. Never prop up a bottle to feed.

Try one new food at a time. Wait 5 days before trying another new food to watch for allergies. Food allergies may include wheezing, rash, or diarrhea.

Introduce peanut butter around 6 months. Spread a small, thin smear of peanut butter or nut butter thinly on a cracker.  Watch your baby for any reaction for the next 2 hours.

Babies under one year should NOT have honey due to the risk of botulism. Also, babies should not have foods that can cause choking like nuts or whole grapes.

All babies are different. Talk with WIC or your baby’s healthcare provider about your baby’s needs.

Feeding Cues

Feeding a 4-5 Month Old

Before teeth come in, wipe gums with a soft, clean wash cloth after each feeding, especially before bed.

Feeding a 0-3 Month Old

Newborns have tiny tummies and need to be fed often. In the first few weeks, you may need to wake your baby to feed if they sleep longer than 4 hours.

Growth Spurts

Many babies are fussy during a growth spurt and will want to nurse longer and more often. This is called cluster feeding. This is your baby’s way of helping you increase your milk supply so that you can keep up with their needs. Remember, the more your baby nurses, the more milk your body makes.

Growth spurts can happen at any time, and every baby is different.

They often happen at these ages:

two-three-weeks

2 to 3 Weeks

6 Weeks

three-months

3 Months

six-months

6 Months
