Should You Start Solids at 4 Months? Signs Your Baby May Be Ready for Solids

So… your baby is 4 months. Now what? 👶🥄

Somehow it’s been both five minutes and five years since you met your baby. You might be packing away the newborn onesies, noticing those chunky thighs, or watching them suddenly seem so much more aware.

This is often the age when feeding questions start bubbling up.
“Should we be starting solids soon?”
“Are they ready?”
“Is milk still enough?”
“Where do I even begin?”

Take a breath. You’re exactly where you’re meant to be. 💛

So, what’s happening at 4 months?

Around this age, many babies are:

• Holding their head steady

• Pushing up during tummy time

• Bringing hands (and everything else) to their mouth

• Watching you eat like it’s the most fascinating show on earth

• Starting to sit with support

These milestones matter because feeding isn’t just about food - it’s about development.

Getting started with eating requires:

• Head and neck control

• The ability to sit upright (with support at first)

• Coordinated swallowing

• A fading tongue-thrust reflex (that automatic “push it back out” move)

Most 4-month-olds are approaching these skills, but not quite there yet. And that’s completely normal.

If you’re not seeing all of these yet, that’s okay. There is no gold star for starting early.
Four months is usually a watching and waiting stage, not necessarily a starting stage. 

The current guidelines tell us that babies should start solids by 6 months of age, and not before 4 months.

So, if they’re doing all of the above, and seem like they’re looking for more to eat between meals…go for it!

But what about nutrition?

This is one of the biggest myths floating around mothers' groups.

For most babies, breastmilk or formula continues to meet their nutritional needs for the first 6 months of life, and continues as the most important source of nutrition until 12 months. Starting solids before 6 months isn’t usually about “needing more food”- it’s about development and exploration when they’re ready.

Around 6 months, babies’ iron stores begin to dip, and that’s when iron-rich complementary foods start to play a more important nutritional role.

At 4 months? Milk is still doing the heavy lifting. 🥛✨

So what can you do right now?

Instead of asking, “What should I feed them?”

Try asking, “How can I prepare us?”

This month can be about:

• Letting baby sit with you at the table

• Talking about what you’re eating

• Watching their cues and curiosity

• Learning about iron-rich first foods

• Thinking about how you’d like your feeding journey to feel

Calm? Playful? Low-pressure? Exploratory?

Because the way we introduce food matters just as much as the food itself.

You don’t have to have it all figured out at 4 months. You’re just gathering information, noticing your baby, and laying the groundwork.

You’re doing beautifully 💛
