YOUR QUESTION. A CLEARER NEXT STEP.
Motor Milestones for a 3-to-6-Month-Old
Between 3 and 6 months, most babies gain steady head control, push up on forearms in tummy time, reach for and grasp toys, bring hands to the midline, and begin rolling. These are gentle guidelines, not deadlines, and babies vary widely.
In this answer 5 sections
Between three and six months, your baby moves from wobbly newness towards purposeful, joyful movement — head steady, hands reaching, body rolling.
In short
Between 3 and 6 months, most babies gain head control, push up on their forearms during tummy time, start reaching for and grasping toys, bring hands to the middle of the body, and begin rolling — usually tummy-to-back first. These windows are gentle guides, not deadlines, and healthy babies vary widely in their pace.
What you may see emerging
Around 3–4 months
- Holds the head steady when held upright, with less wobble
- During tummy time, props up on forearms and lifts the chest
- Brings both hands together over the chest and to the mouth
- Begins to reach out and swipe at dangling toys
- May start pushing down on legs when feet touch a firm surface
Around 5–6 months
- Rolls from tummy to back (and some babies the other way too)
- Reaches with one hand and grasps a toy, passing it between hands
- Sits with support, head and back becoming steadier
- Pushes up onto straight arms during tummy time
- Bears some weight on legs when held in a standing position
Daily tummy time while awake and supervised is the single best way to build the neck, shoulder and core strength behind all of these.
When to mention it at your check-up
Milestones arrive on a range, so a few weeks' variation is normal. Do raise it gently with your paediatrician if by around 6 months your baby still has marked head lag when pulled to sit, isn't reaching for objects, feels persistently very stiff or very floppy, isn't bearing any weight on legs, or has lost a skill they once had. These deserve a friendly, prompt look — not worry.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
By around 6 months, mention it at your check-up if your baby still has marked head lag when pulled to sit, isn't reaching for toys, feels very stiff or very floppy, bears no weight on legs, or has lost a skill they once had.
In everyday life
Offer short, supervised tummy-time sessions several times a day while your baby is awake — it builds the neck, shoulder and core strength behind nearly every motor milestone at this age.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
When do babies start rolling over?
Many babies begin rolling from tummy to back around 4–5 months, with back-to-tummy often following a little later by 6 months or beyond. Some roll earlier, some later — both are normal. Plenty of supervised tummy time helps build the strength for it.
Is it normal if my 6-month-old isn't sitting unsupported yet?
Yes — independent sitting often develops between 6 and 9 months. At 5–6 months many babies only sit with support while their back and head grow steadier. If you have any concerns, mention them at your routine check-up for reassurance.
How much tummy time does a baby this age need?
Aim for several short, supervised sessions across the day while your baby is awake, gradually increasing as they enjoy it. Tummy time strengthens the neck, shoulders and core that power head control, reaching and rolling.
Should I worry if my baby reaches more with one hand?
Reaching with either hand is fine at this age. A strong, consistent preference for one hand before about 12 months is worth mentioning to your paediatrician, but occasional one-handed reaching while exploring is completely normal.
