Why Babies Under 6 Months Should Stick with Just Breastmilk or Formula

Thanksgiving is around the corner, and with all the food, family gatherings, and well-meaning aunts offering “just one little taste,” it’s a perfect time to remind ourselves of what really supports our tiniest babies. If your baby is under 6 months old, here’s why the best “plate” they need is simply breastmilk or formula — and why introducing solids too early can create more problems than memories.

1. The Quiet Power of Breastmilk/Formula

From the start, breastmilk (and when needed, formula) is enough. According to the World Health Organization (WHO), infants should be exclusively breastfed for the first six months of life to achieve optimal growth, development and health. World Health Organization+2World Health Organization+2That means: no other food, no “just a taste,” no water or solids (unless medically indicated).

Why? Because breastmilk (and appropriate formula) contains the nutrients your baby needs in the early months — and it supports protection from infections, supports the brain, digestion, and more. Baby-Friendly USA+1

2. Their Bodies (and Brains) Are Still Developing

Young infants are still learning key skills: how to swallow safely, how to digest food, how to self-regulate what and how much to eat. According to the American Academy of Pediatrics (AAP) policy statement: complementary solids should be introduced at about 6 months for most infants. Pediatrics Publications One practical note: prior to about 6 months, many babies still have the tongue-thrust reflex (they push things out), or aren’t sitting with support, which means introducing solids could increase choking risk or frustration. ucsfbenioffchildrens.org+1

3. Introducing Solids Too Early Can Create Risks

While it’s tempting (“Oh, my baby wants what I’m eating!”), evidence shows that there are downsides to starting solids too early (before around 6 months or before developmental readiness).

• One study found that infants introduced to solid foods “tiny tastings” before 6 months had shorter durations of exclusive breastfeeding and may have higher odds of consuming non-recommended foods. BioMed Central

• Another research note found early solids (before 3-4 months) trigger changes in the gut microbiome that may lead to higher risk of obesity or metabolic challenges later. Bloomberg School of Public Health

• Additional insights: Introducing food too early can reduce breastmilk intake, which may reduce milk supply and cause earlier weaning. Nest Collaborative

Bottom line: Waiting until around 6 months (and baby showing signs of readiness) gives your baby a strong start.

4. So, What Happens Around 6 Months (and Why That Timing)?

By around age 6 months, your baby’s nutritional needs start to exceed what breastmilk or formula alone can supply — particularly iron and other minerals. The WHO notes that around six months is a time when complementary foods become necessary while continuing breastfeeding. World Health Organization some of the “readiness” signs include: baby can sit with minimal support, can hold their head steady, shows interest in food, has lost the tongue-thrust reflex, and other developmental markers. ucsfbenioffchildrens.org

When you introduce complementary foods at the right time and appropriately, it supports growth, good feeding habits, and fewer challenges down the road.

5. A Gentle Strategy for Mamas: What to Say at the Table

When Aunt Linda or a well-meaning cousin says “Here, let baby try a little bite of ____,” you’re empowered to set gentle, confident boundaries.

Here are phrases you can keep handy:

“We’re waiting until baby is around six months and developmentally ready — thanks for understanding.

” We’re sticking to breastmilk/formula for now — this helps their tummy and feeding rhythm stay strong.”

"We’ll introduce solids when our INFANT FEEDING SPECIALIST (IBCLC) says it’s time and baby shows signs of readiness"

— today they get the snuggles instead of the sweet potato casserole.

Because your baby doesn’t need the casserole to feel included. They are included. Their joy at the table happens through the family being present, the hugs, the sounds, the smiles.
