Baby’s First Year:
The Ultimate Guide for 0–12 Months
From first smiles to first foods, this is your complete, science-backed guide for baby’s first year of milestones, sleep, play, and wonder.
Explore Milestones By Age
Developmental Milestones: 0-12 Months
Watch your baby grow! Here’s what to expect in the major areas of development. Use the interactive checklists to track your baby’s progress.
Welcome to the World: 0–3 Months
Brain Booster: “Serve & Return” Chats
When your baby coos (a “serve”), respond with words and a smile (a “return”). This back-and-forth builds crucial brain connections for language and social skills.
Interactive Checklist
Discovery Time: 4–7 Months
Brain Booster: Object Permanence
Partially hide a toy under a blanket. Ask, “Where did it go?” to teach them that things exist even when they can’t be seen—a huge cognitive leap.
Interactive Checklist
On the Move: 8–12 Months
Brain Booster: Container Play
Give them a safe box and blocks. Practicing putting items in and taking them out builds fine motor skills and an understanding of cause-and-effect.

First Foods Adventure
Introducing solid foods around 6 months is a messy, fun, and important milestone. Here’s how to know if your baby is ready.
Is Baby Ready for Solids? Checklist
Purees vs. Baby-Led Weaning (BLW)
There are two popular methods. You can choose one or combine them!
🥄 Traditional Purees
Start with smooth, single-ingredient purees (like avocado, banana, or sweet potato) and gradually introduce thicker textures and combinations.
🖐️ Baby-Led Weaning (BLW)
Offer baby soft, finger-sized pieces of whole foods (like steamed broccoli florets or strips of toast) to self-feed. This promotes motor skills and self-regulation.
Secrets to Sweeter Sleep
Infant sleep is a journey, not a destination. Use our interactive calculator to understand your baby’s needs and learn the foundations of healthy sleep habits.

Safe Sleep Foundations
- Back to Sleep: Always place baby on their back for all sleep.
- Firm, Flat Surface: Use a crib or bassinet with a firm mattress and a fitted sheet.
- Empty is Best: Keep the sleep space free of blankets, pillows, bumpers, and toys.
Brain-Building Play Ideas
Fuel your baby’s development with these simple activities. The best toy is you! Filter by the skill you want to focus on.
Pillow Mountain
Create a small, soft “mountain” of pillows for your baby to crawl over. This builds strength, balance, and coordination.
💪 Motor SkillsSensory Basket
Fill a basket with safe items of different textures: a soft cloth, a bumpy ball, a smooth wooden block, and a crinkly toy.
🖐️ Sensory“Point & Name” Tour
Carry your baby around the house, point to objects, and name them clearly. “Look, a shiny, red apple.” Repetition is key.
🗣️ LanguageRead Aloud
It’s never too early! Choose board books with bright pictures. Your baby loves the sound of your voice and learns the rhythm of language.
🗣️ LanguageTummy Time Tracker
Place a baby-safe mirror just in front of them during tummy time. Watching themselves move encourages them to lift their head.
💪 Motor SkillsWater Play
In a shallow pan with a little water, let your baby splash with their hands. Supervise closely! It’s a wonderful sensory experience.
🖐️ SensoryBall Roll
Sit on the floor opposite your baby and roll a soft ball back and forth. This teaches turn-taking and develops hand-eye coordination.
💪 Motor SkillsSing-Song Fun
Sing simple, repetitive songs with hand motions like “The Wheels on the Bus.” The melody and actions capture their attention.

You know your baby best. While all babies develop at their own pace, this guide can help you spot potential delays. Trust your instincts—if you have a concern, it’s always worth asking.
By 3-4 Months, check in if baby:
- Doesn’t respond to loud sounds.
- Doesn’t follow moving objects with their eyes.
- Doesn’t bring hands to mouth.
- Has trouble lifting their head during tummy time.
By 7 Months, check in if baby:
- Seems very stiff with tight muscles, or very floppy like a rag doll.
- Doesn’t roll over in either direction.
- Doesn’t babble or try to make sounds.
- Doesn’t reach for things or show affection for caregivers.
By 12 Months, check in if baby:
- Doesn’t crawl or drags one side of the body while crawling.
- Cannot stand when supported.
- Doesn’t search for things that they see you hide.
- Doesn’t say simple words like “mama” or “dada”.
- Doesn’t use gestures, like waving or pointing.
Feeling concerned? It’s okay. Early support makes all the difference. Get professional guidance without the wait.

The first year is full of advice. Here’s what science says about the most common worries parents have.
Responding to your baby’s cries builds secure attachment. This secure base gives them the confidence to explore the world and become independent later on. It’s a biological need, not a behavioral issue.
Babies’ sleep cycles are shorter than adults’, and waking frequently is a normal, protective mechanism. The goal is to establish predictable, calming routines and a safe sleep environment. Consistent sleep patterns emerge as their brain matures.
Major pediatric associations advise against walkers. They can tip over easily and allow babies to reach dangerous things. Barefoot time on the floor is the best way to encourage natural walking development.
The most powerful driver of learning is “serve and return” interaction with a caring adult. Talking, singing, and reading build their brain architecture far more effectively than any flashy toy.
