The 4-month appointment ends with your pediatrician saying something like: "She's doing great — you can start thinking about solids soon."
You nod. You say great. You go home and immediately realize you have no idea what that actually means.
When exactly? What food first? How much? Does milk stop? What if she hates everything? Do you need special equipment or can you just mash a banana?
This guide answers all of it — in the order you'll actually need it.
Signs Your Baby Is Ready
Age is a guideline, not a rule. Before starting solids, look for these signs:
Head control. Baby can hold their head steady and upright without support. This is non-negotiable — swallowing solid food safely requires it.
Sitting with support. Baby can sit in a high chair or supported seat without slumping. They don't need to sit independently, but they need to be upright.
Interest in food. Baby watches you eat, reaches toward food, or opens their mouth when they see a spoon coming. This is a big one — disinterest often means they're not ready yet.
Tongue-thrust reflex fading. Young babies automatically push things out of their mouth with their tongue. When this reflex fades, food stays in instead of getting pushed back out. If you try a spoon and everything comes right back out, wait a week or two and try again.
Weight. Most babies who are developmentally ready weigh roughly double their birth weight — usually around 13–15 pounds.
If your baby checks most of these boxes between 4 and 6 months, they're likely ready. If you're not sure, your pediatrician is the best person to ask at the next visit.
What to Start With
Single-ingredient purees. That's it. One ingredient, smooth texture, small amounts.
Good first foods:
- Sweet potato
- Butternut squash
- Peas
- Pears
- Applesauce
- Avocado
- Banana
- Rice or oatmeal cereal (iron-fortified)
The 3-to-5-day rule: Introduce one new food at a time and wait 3 to 5 days before introducing another. This waiting window exists so you can clearly identify any allergic reaction or sensitivity. If baby tries sweet potato Monday, don't add peas until Thursday or Friday.
On fruit vs. vegetables: You've probably heard to start with vegetables so baby doesn't develop a preference for sweet foods. The research doesn't strongly support this — babies are born with a preference for sweet flavors and that doesn't change based on introduction order. Start with whatever you have and whatever your pediatrician recommends.
How Much to Start With
Less than you think.
Week 1: 1–2 teaspoons per sitting, once a day Week 2–3: 1–2 tablespoons, once or twice a day By 6–7 months: 2–4 tablespoons, working toward two or three small meals
These are starting points, not rules. Follow your baby's cues. Some babies take to solids immediately and want more; others pick at tiny amounts for weeks. Both are normal.
The Schedule: Solids Alongside Milk Feeds
For the first few months, milk is still the primary nutrition. Solids at this stage are about learning — learning textures, flavors, and the mechanics of eating. The calories still come mostly from breast milk or formula.
A practical daily structure:
| Time | What |
|---|---|
| Morning | Milk feed first |
| Mid-morning | Solid food (1–2 tbsp) — 30–60 min after milk |
| Afternoon | Milk feed |
| Evening | Solid food (1–2 tbsp) — optional second meal |
| Before bed | Milk feed |
The key principle: offer milk first, then solids. This protects milk intake and supply while baby is learning to eat. As they approach 8–9 months and take larger volumes, the order naturally shifts.
Tracking this schedule alongside your regular feed log is easier than it sounds. Once solids enter the picture you're managing more variables — which new food you introduced, whether baby reacted, how much they actually ate. Having a log you can reference at the pediatrician visit is genuinely useful.
Mommy's Log tracks bottle feeds, breastfeeding sessions, and — with a quick note — which solids you've introduced. Free, no account, everything on your device.
What You Actually Need
You don't need much. But two things make a real difference:
A High Chair That's Easy to Clean
Solids are messy. Not "wipe it down" messy — "how did pureed sweet potato get on the ceiling" messy. A high chair with a removable, dishwasher-safe tray and smooth surfaces without crevices where food hides makes the cleanup actually manageable.
This high chair has been a staple in our house through two kids. The tray pops off and goes straight in the dishwasher, the seat wipes clean completely, and it grows with baby from early solids through toddler meals. When you're cleaning up three times a day, easy-clean design stops being a nice-to-have.
A Baby Food Maker
Buying pouches and jars is convenient. Making your own means you know exactly what's in every batch — no additives, no preservatives, no mystery ingredients on labels you have to decode at 6am.
The practical barrier has always been time. A good baby food maker removes it: steam and blend in the same bowl, done in minutes.
This baby food maker is the one we've used for both of our kids. The glass bowl is the detail that matters — it doesn't absorb stains or odors the way plastic does, it's dishwasher safe, and you're not heating food in plastic every day. For something baby eats from multiple times a day, every day for months, that's worth it. It's easy to clean and simple enough to use one-handed while holding a curious baby with the other.
A batch of sweet potato puree takes about 12 minutes start to finish. You can make a week's worth on Sunday and refrigerate or freeze in ice cube trays.
Common Mistakes
Starting too early. Before 4 months, baby's digestive system is not ready. Early solids are linked to higher allergy risk and digestive issues. If your doctor recommends waiting, wait.
Skipping milk feeds to "make room." Milk calories are denser than purees. Replacing a milk feed with solids too early can reduce calorie intake. Always offer milk first.
Giving up after one rejection. Research shows babies may need to be offered a new food 10 to 15 times before accepting it. One turned-up nose is not a verdict. Try again in a few days.
Not waiting between new foods. The 3-to-5-day rule feels slow. Skip it once, baby reacts to something, and you have no idea which of the three new foods you introduced that week caused the problem.
Forgetting water. Once solids start, small amounts of water (1–2 oz with meals) can help prevent constipation as the digestive system adjusts.
Tracking New Foods
Your pediatrician will ask what you've introduced and whether you've noticed any reactions. Most parents try to recall this from memory — and can't.
A simple log of what you introduced and when takes 10 seconds per entry and makes that conversation genuinely useful. It also helps you track patterns: is baby consistently less settled after a specific food? Does she seem gassier on days you give peas?

Starting solids is one of those parenting milestones that feels enormous before you do it and normal about a week in. The first few times are messy and tentative and often end with more food on the bib than in the baby. That's fine. That's exactly right.
