Difficulty: EasyDevelopmental Stages and Transitions

A practical nurse is reviewing developmental milestones with new parents at a pediatric clinic. Arrange the following infant gross motor skills in the chronological order in which they are typically achieved, from earliest to latest.

  1. 1Lifting the head and chest while in a prone position
  2. 2Rolling from the abdomen to the back
  3. 3Sitting independently without support
  4. 4Pulling up to a standing position

Answer

The earliest skill is lifting the head and chest, followed by rolling from the abdomen to the back, then sitting independently without support, and finally pulling up to a standing position.
Gross motor development follows a predictable cephalocaudal (head-to-toe) pattern. Infants first gain control of their neck and upper body, allowing them to lift their head and chest. As strength moves down the trunk, they learn to roll over. Continued core development subsequently allows for independent sitting. Finally, strength and coordination reach the lower extremities, enabling the infant to pull up to a stand in preparation for walking.

Step-by-Step Solution

1
Identify the skill that occurs first based on cephalocaudal (head-to-toe) development.
Lifting the head and chest is selected as the first milestone.
Head and neck control are the earliest gross motor skills to develop, typically by 2 to 3 months of age.
2
Identify the next milestone involving initial trunk control and weight shifting.
Rolling from the abdomen to the back is selected as the second milestone.
Infants learn to use their upper body strength to shift their weight and roll over, usually around 4 to 5 months.
3
Determine the skill requiring significant lower back and core stability.
Sitting independently without support is selected as the third milestone.
Core strength must be fully established before an infant can maintain an upright seated position safely, typically seen at 6 to 8 months.
4
Identify the milestone involving the lower extremities and preparation for walking.
Pulling up to a standing position is selected as the final milestone in this sequence.
Leg strength and overall body coordination develop last in this sequence, allowing the infant to bear weight and stand, usually by 9 to 11 months.
