Is My 3-to-6-Month-Old Developing Normally in Adaptive Skills?
Between 3 and 6 months, most babies make big strides in adaptive skills — reaching, grasping, bringing hands and objects to the mouth, and showing curiosity about food and faces. Wide variation is normal. A gentle developmental check is wise only if, around 5–6 months, your baby isn't reaching at all, keeps hands tightly fisted, or shows little interest in objects and people — reasons to look, not a diagnosis.
Watching your baby reach, grasp and bring everything to their mouth — those small, busy hands are doing big developmental work.
In short
Between 3 and 6 months, most babies make wonderful leaps in adaptive skills — the everyday hands-on abilities like reaching for toys, grasping, bringing hands and objects to the mouth, and starting to show interest in food and faces. Wide variation is completely normal, and a baby finding their own pace is usually thriving. A gentle developmental check is wise only if your baby isn't reaching for things at all by around 5–6 months, keeps their hands tightly fisted, or seems uninterested in objects and people — these are reasons to look, not a diagnosis.What to expect at 3–6 months
Adaptive development at this age is mostly about hands, mouth and curiosity working together:- Reaching and swiping — by 4–5 months many babies bat at and then reach for toys, and start transferring objects.
- Grasping — fingers open and close around a rattle; by 6 months many can hold and shake a small toy.
- Hand-to-mouth — bringing hands and objects to the mouth is healthy exploring, not a worry.
- Visual interest — following objects with their eyes, looking at hands, watching faces closely.
- Early feeding readiness — towards 6 months, showing interest in what others are eating and good head control for sitting supported.
Babies vary enormously, and a few weeks either way is typical — especially for babies born early, where you'd gently count from the due date.
When a check is wise
Arrange a calm developmental review if, around 5–6 months, your baby is not reaching for objects at all, keeps hands persistently fisted, doesn't bring hands together or to the mouth, or shows little interest in toys, faces or their surroundings. Trust your daily observations — what you notice matters, and early looking simply opens early opportunities.The Pinnacle way

What to watch
Seek a developmental check if, around 5–6 months, your baby is not reaching for objects at all, keeps hands persistently fisted, doesn't bring hands together or to the mouth, or shows little interest in toys, faces or surroundings. For babies born early, count gently from the due date.
Try this at home
Offer a light rattle or soft toy just within reach during floor or lap time, and watch how your baby reaches and grasps. A few minutes of supervised play each day gives those busy hands plenty of practice — and you a clear picture of progress.

Frequently asked
What are normal adaptive skills for a 3-to-6-month-old?
Reaching for and grasping toys, transferring objects, bringing hands and objects to the mouth, watching faces and following objects with the eyes, and — towards 6 months — showing interest in food and good head control when sitting supported. Wide variation is completely normal.
My baby keeps putting everything in their mouth — is that a problem?
No, this is healthy and important. Bringing hands and objects to the mouth is how babies at this age explore texture and shape. Just keep small or unsafe items out of reach.
When should I worry about my baby's adaptive development?
A gentle developmental check is wise if, around 5–6 months, your baby isn't reaching for objects at all, keeps hands tightly fisted, doesn't bring hands together, or shows little interest in toys and people. This is a reason to look, not a diagnosis.
My baby was born early — should I adjust my expectations?
Yes. For babies born before their due date, gently count milestones from the corrected age (the due date rather than the birth date) for roughly the first two years.
