A child ages 3 to 6 months can be expected to:
- May roll from side to side.
- May sit with support.
- Holds head steady and erect.
- Laughs aloud.
- Reaches and grasps some objects.
- Shakes rattle when placed in hand.
- Puts everything into mouth.
- Turns head purposefully in response to human voice.
- May turn purposefully from back to side to stomach.
- Begins to hold a bottle.
- May begin teething.
- May express fear toward unfamiliar people.
Each child is unique. It is therefore difficult to describe exactly what should be expected at each stage of a child's development. While certain milestones tend to occur at certain ages, a wide spectrum of growth and behavior for each age is normal. Consequently, these guidelines are offered as a way of showing a general progression through the developmental stages rather than as fixed requirements. It is perfectly natural for a child to attain some milestones earlier and other milestones later than the general trend. Keep this in mind as you review these milestones.
If you have any concerns related to your child's own pattern of development, check with your physician.
