6-Month Baby Milestones: What to Expect and How to Support Your Baby’s Development?
Wasn’t it just yesterday that you held your tiny newborn in your arms? And now, here they are—already six months old, full of curiosity, giggles, and newfound skills. This stage is a beautiful mix of excitement and questions—are they developing as they should? Should they be sitting up, babbling more, or reaching for things? Every baby grows at their own pace, but knowing the key 6 month milestones can help you cherish their progress with confidence. So, let’s explore the wonderful changes your little one might be experiencing at six months.
6 Month Baby Milestones: Growth
When it comes to baby development at 6 months, your little one’s growth continues, but the rapid weight gain of the newborn phase starts to slow down. This is completely natural as they become more active and burn more energy. On average, a 6-month-old baby boy weighs around 7.90 kg and measures about 26.5 inches in length, while a 6-month-old baby girl typically weighs 7.30 kg and is about 26 inches long. However, every baby grows at their own pace, and slight variations are completely normal. If you’re concerned about your little one’s development, consulting their paediatrician can help ensure they are on track.
6 Month Old Milestones: Motor Skills and Physical Development
At six months, your baby is gaining strength and control over their movements. Here are the key 6 month old baby milestones related to physical development and motor skills:
- Rolling Over with Ease: Your baby has likely mastered rolling from their tummy to back and is now rolling in both directions. This means they can shift positions independently, making diaper changes a bit more challenging.
- Sitting with (or Without) Support: At this stage, babies start sitting upright. Initially, they lean on their hands for balance, but with time, they develop stronger core muscles and can sit unsupported. Many can now sit steadily in a high chair, which is great for mealtime.
- Leg Strength and Bouncing Fun: Your little one is getting stronger. When held upright, they push down on their legs against a firm surface and may even start bouncing up and down. Many babies love this movement and enjoy time in a baby bouncer.
- Rocking in Preparation for Crawling: Some babies begin rocking back and forth on all fours, preparing for crawling. While a few may start crawling at this age, most will take a few more months before they start moving independently.
- Improved Hand Coordination: Your baby’s hand skills are becoming more refined. They can now grab objects and bring them closer, pass items from one hand to another, and even let go of objects intentionally.

6 Month Milestones: Cognitive and Sensory Development
At six months, your baby’s brain is growing rapidly, and they are becoming more curious about the world around them. Here are the key 6 month old baby milestones related to cognitive and sensory development:
- Exploring Through the Mouth: Your baby is in full exploration mode, and their favorite way to learn is by putting objects in their mouth. This helps them understand textures, shapes, and even tastes.
- Showing Preferences and Making Choices: By six months, babies begin expressing likes and dislikes. If they don’t want more food, they may close their lips tightly. Similarly, they reach for toys they want and ignore the ones they aren’t interested in.
- Recognising Familiar Faces: Your baby can now differentiate between familiar people and strangers. They may react with excitement when they see a parent or caregiver and show hesitation or wariness around unfamiliar faces.
- Recognising Their Name: At six months, many babies start responding to their name. If you call them, they may turn their head or smile, showing early language recognition.
- Increased Curiosity About Their Surroundings: Your baby will spend a lot of time observing their environment, watching objects move, and reaching for things just beyond their grasp. This curiosity drives learning, so providing colourful, textured toys and safe household objects can keep them engaged.
6 Month Old Milestones: Social and Emotional Development
At six months, babies are becoming more expressive and social, responding to the people and emotions around them. Here are the key 6 month milestones related to social, emotional, and communication skills:
- Enjoying Mirror Time: Babies at this stage love looking at their reflection in mirrors. They may smile, laugh, or even try to interact with their “mirror friend,” which helps them develop self-awareness.
- Responding to Emotions: Your baby is becoming more in tune with emotions. They can sense when you’re happy, sad, or stressed and may react accordingly. If you smile, they may smile back; if you seem upset, they might fuss or cry in response.
- Expressing Happiness Through Laughter: Laughter becomes a regular part of their interactions. They giggle when tickled, react joyfully to playful sounds, and enjoy silly games like peek-a-boo.
- Taking Turns in Communication: Your baby is starting to engage in simple conversations! They enjoy taking turns making sounds with you and may respond to your voice with babbling, squealing, or blowing raspberries.
- Early Speech Development: Your baby’s vocal skills are improving, and they are experimenting with different sounds. They may start repeating syllables like “baba” or “dada” and love it when you mimic their sounds, encouraging them to continue learning language.
- Playtime and Social Interaction: Playing is a key part of social development. Babies at this age love interactive games like pat-a-cake and peek-a-boo. These games help them learn about cause and effect, memory, and turn-taking.

6 Month Baby Milestones: Nutrition and Feeding
While 6 month old baby milestones vary from child to child, this is generally the time when parents can begin introducing complementary foods alongside breast milk or formula. Not all babies are ready for solids right at six months, but some common indicators include:
- Having good head and neck control
- Sitting upright with minimal support in a high chair
- Opening their mouth eagerly when food is offered
- Moving food toward the back of the mouth instead of pushing it out with their tongue
- Bringing hands or objects to their mouth frequently
If your baby hasn’t yet shown these signs, there’s no rush—every baby develops at their own pace.
Traditionally, parents started with iron-fortified infant cereals, but it’s not a necessity. Some great first foods include:
- Mashed or pureed vegetables such as squash, sweet potatoes, and carrots
- Pureed fruits like applesauce, peaches, bananas, and pears
- Pureed meats for protein and iron intake
It’s common for babies to reject solid foods initially. If your little one turns away or refuses, don’t be discouraged. Keep offering the food in small amounts—sometimes it takes multiple tries before a baby accepts a new taste or texture.
Even with the introduction of solids, breast milk or formula remains the primary source of nutrition. A 6-month-old typically needs 790–900 grams of breast milk or formula daily, spread across five to six feedings. This ensures they get all the essential nutrients required for healthy growth. For breastfed babies, nursing isn’t just about nutrition—it also provides comfort. As they experience rapid growth and developmental changes, they may nurse more frequently for reassurance and bonding, which is completely normal.
6 Month Milestones: Sleep Patterns
By six months, many babies develop a more predictable sleep schedule, though sleep needs can vary. On average, a 6-month-old requires 12 to 16 hours of total sleep per day, including both nighttime sleep and naps. A typical pattern may involve about 10 hours of sleep at night and 4 hours spread across two to three daytime naps.
Most babies at this stage begin sleeping for longer stretches at night, and some may even sleep through the night. However, it is still normal for babies to wake up occasionally, sometimes for a feeding or due to changes in their sleep cycle. Some babies may also start resisting naps or bedtime because they are excited about exploring the world around them.
Around this age, some babies experience sleep regression, where they struggle to fall asleep or wake up more frequently. This can happen as they develop new skills and become more aware of their surroundings. If your baby’s sleep routine seems disrupted, maintaining a consistent bedtime routine and ensuring a soothing sleep environment can help.
Ensuring a dry and comfortable diaper is crucial for uninterrupted sleep, and Teddyy Baby Diapers can help with that. Designed for superior absorption and long-lasting dryness, Teddyy Diapers prevent leakage and discomfort, allowing babies to sleep peacefully through the night. The soft, breathable material provides maximum comfort, ensuring a soothing sleep environment that can help foster healthier sleep patterns.
Conclusion
Your baby’s journey through their 6 month milestones is a beautiful mix of growth, discovery, and endless wonder. Every little giggle, every attempt to sit up, and even the occasional sleepless night is a step toward something amazing. While this phase comes with its share of challenges—fussy feedings, sleep regressions, and teething discomfort—remember that you’re doing an incredible job. Creating a nurturing environment, filled with love, comfort, and care, can make all the difference.
A 6-month-old baby is typically rolling over, sitting with support, babbling, recognizing familiar faces, and reaching for objects. They also show curiosity about their surroundings, respond to their name, and may start exploring solid foods.
By six months, babies can roll over both ways, sit with or without support, push down on their legs when held upright, and grasp objects with better hand coordination. Some may also rock back and forth in preparation for crawling.
Red flags include lack of eye contact, not responding to sounds, difficulty holding up their head, inability to roll over, no interest in reaching for objects, and lack of social engagement. If concerned, consulting a pediatrician is recommended.
At six months, babies need proper nutrition (breast milk/formula and possibly solids), safe toys for sensory exploration, a comfortable sleeping space, and lots of interaction for cognitive and emotional development. Supportive diapers like Teddyy can help ensure comfort.
