Is Your Baby Ready for Solids?

A free tool based on WHO principles and responsive feeding, designed to help you understand when and how to start solids the right way.

🥄 Starting Solids

A short, professional tool for parents to assess physical, developmental, and environmental readiness before starting solids

This readiness tool helps parents look beyond age alone and better understand whether a baby may be ready to begin complementary feeding.

Why not start complementary feeding based only on age?

Chronological age is only part of the picture. Starting complementary feeding before a baby is ready may lead to coughing, frustration, a negative feeding experience, and even safety concerns. A readiness assessment looks at a combination of motor ability, developmental interest, environmental conditions, and individual factors — not just whether it feels like “the right time.”

What does the readiness assessment check?

🟢 Motor and safety readiness

Head control, sitting stability, and response to a spoon.

🔵 Developmental readiness and interest

Hand-to-mouth coordination, opening the mouth, and interest in food.

🟠 Individual considerations

Prematurity, weight gain, iron status, and current feeding pattern.

🟣 Environment and responsive feeding

Positioning, pace, adult attention, and food texture.

Complementary Feeding Readiness Assessment

A quick parent check based on global health principles and responsive feeding

Welcome 👋

This tool checks physical, developmental, and environmental readiness
to help you understand when and how to start complementary feeding.

Who is this for? Healthy infants around 4–7 months of age.
Time to complete: About 1 minute.

Step 1/4: Motor Readiness (Safety)

These are key safety foundations. Before starting solids, it is important to make sure your baby has good head control, can sit stably, and can manage a spoon safely. If you are unsure, choose “Not sure”.

4. Comfort with mouth contact When an empty spoon gently touches the lips or tongue, is your baby usually comfortable without frequent coughing, gagging, or distress?

Step 2/4: Developmental Readiness (Interest)

Eating is a learned skill. Here we look at interest, coordination, and the ability to sit calmly during feeding.

Illustration of a baby showing interest in food 6. Does your baby show interest in your food? For example: watching you eat, reaching toward the plate, or making chewing motions.
7. Mouth opening When you bring a spoon close (empty or with a tiny amount), does your baby open the mouth voluntarily?
8. Stability and calm while sitting Is your baby usually calm while sitting, without significant arching or strong stiffness?

Step 3/4: Personal Considerations

Here we identify factors that may call for extra adjustment or professional guidance, such as prematurity, growth concerns, or iron status.

9. Was your baby born premature? A factual definition: preterm means birth before 37+0 weeks.
10. Is weight gain on track? Based on recent measurements with your pediatrician or clinic.
11. Current feeding pattern Is your baby exclusively breastfed, with no formula at all?
12. Iron What is known about iron deficiency or anemia? If no tests were done, choose “Not tested”.

Step 4/4: Environment and Conditions

These are the conditions for safe and successful feeding, in line with responsive feeding principles.

13. Is your baby sitting in a safe and stable position? A fairly upright position with appropriate support helps reduce risk.
14. Is a focused adult present during feeding? Without phone, TV, or other distractions, so hunger and fullness cues can be noticed.
15. Feeding pace Is feeding done slowly and according to your baby’s hunger and fullness cues?
16. Food texture Is the offered food soft or pureed, without unsafe lumps, and appropriate for this stage?

How to understand the result

🟢 Good readiness

You can begin complementary feeding gradually and safely.

🟡 Partial readiness

A cautious start, some adjustments, or professional guidance may be helpful.

🔴 Not yet

It is best to wait and work on the key readiness foundations first.

This tool was developed by KidGil
by a certified pediatric dietitian, based on clinical experience and daily work with parents and babies.

Its goal is to make professional, reliable, and clear knowledge about starting complementary feeding more accessible — without fear and without pressure.

The tool is based on the principles and recommendations of the World Health Organization (WHO) regarding complementary feeding for infants.

❓ Parent FAQ

Frequently Asked Questions About Complementary Feeding

Clear, practical answers for parents who want to better understand when and how to start solids.

At what age can babies start complementary foods?

In most cases, complementary feeding begins around 6 months of age. However, it should start only when the baby shows clear readiness signs — not based on age alone.

Are breastfed babies ready later?

Not necessarily. Breastfed babies may start complementary feeding at a similar time as other babies. However, it is especially important to include iron-rich foods once solids begin.

Does prematurity affect the start of solids?

Yes. For babies born prematurely, professionals often consider the corrected age rather than the chronological age. In many cases, professional guidance is recommended when introducing complementary feeding.

Is this tool suitable for babies aged 4–5 months?

Yes. The tool can also be used for younger babies around 4–5 months. However, it is not designed to approve starting solids at this age.

Instead, it helps identify early signs of readiness or areas that are not yet mature. At this stage, it is very common to receive a result such as “partial readiness” or “not yet”, and that can be completely normal.

The goal is to help parents understand what may still be developing — such as head control, sitting stability, interest in food, or the feeding environment — and when it may be appropriate to check again.

In most cases, the recommendation will still be to wait and continue breastfeeding or formula feeding until fuller readiness develops.
