Your 6-Month-Old Baby: Milestones & What to Expect

Development at Six Months

Many six-month-olds roll confidently in both directions, sit with a little support, and pass toys from hand to hand. Your baby's view of the world is changing as they spend more time upright, and their curiosity grows with it.

Cognitively, an early sense of object permanence is forming — your baby is beginning to understand that things (and people) still exist when out of sight, which is partly why peek-a-boo becomes so delightful. Babbling with consonants like 'ba' and 'ma' often begins around now too.

• Sitting with support: With a cushion or your hands for balance, your baby can often sit and explore toys from a new angle.
• Passing objects: Moving a toy from one hand to the other shows growing coordination and body awareness.
• Babbling: Early consonant-vowel sounds are the start of real speech development.

Starting Solid Food

Around six months, most babies are ready to begin complementary foods alongside breastmilk or formula. Signs of readiness include good head control, sitting with support, and the ability to move food to the back of the mouth rather than pushing it out.

Milk remains the main source of nutrition in these early weeks of solids. Offer a variety of tastes and textures, keep salt and added sugar to a minimum, and introduce common allergens (such as egg and peanut) early and one at a time, in line with current guidance that early introduction may help reduce allergy risk.

• Responsive feeding: Let your baby decide how much to eat. Stopping when they turn away or lose interest helps them tune in to their own fullness.
• Allergen introduction: Introduce common allergens one at a time in small amounts and watch for any reaction; discuss any family allergy history with your health professional.
• Iron matters: Iron-rich foods like pureed meat, beans, or iron-fortified cereals become important as stores from pregnancy begin to deplete.

Sleep at Six Months

Many babies sleep for longer stretches at night by six months, with daytime sleep settling into around 2–3 naps. A consistent bedtime routine and a regular first nap can help the day feel more predictable.

Separation anxiety and developmental leaps can still disrupt sleep from time to time. A calm, predictable wind-down and putting your baby down drowsy but awake when you can helps build independent settling skills.

• Predictable routine: Consistent sleep cues at the same time each day help your baby know what is coming next.
• Gentle independent settling: Placing your baby down drowsy but awake, when practical, supports self-settling.

Crying & Soothing

With greater awareness comes stronger preferences, so you may notice more protest crying — for example when a toy is taken away or you leave the room. This is a sign of growing attachment and understanding, not naughtiness.

Familiar soothers still help, and your increasingly aware baby will respond well to distraction, songs, and being included in what you are doing.

• Name the feeling: Even simple, calm narration ('I see you wanted that') supports early emotional development.
• Redirection: Offering a different toy or changing scenery can gently ease protest and overstimulation.

Conclusion

Six months is a beautiful turning point — food, movement, and personality all blossom at once. Follow your baby's lead, keep mealtimes relaxed, and enjoy watching their world expand. You are guiding them through one of the richest stages of the first year.
