Question 1

When does the third growth spurt occur?

Accepted Answer

Usually the third growth spurt occurs around 11–12 weeks of life, when the baby's perception of light, sound, and movement becomes more refined and attention to faces and objects increases. During this period the baby can track moving objects for longer and becomes more responsive to environmental changes as the nervous system develops rapidly.

Question 2

Why does the baby cry when the mother leaves?

Accepted Answer

Often this is due to separation anxiety that appears at this stage when the baby begins to understand that the mother is a separate person who can leave. Because of this, the baby seeks more closeness, cries more frequently, and needs reassurance through physical presence as their sense of safety is still developing.

Question 3

How can you help the baby during the third growth spurt?

Accepted Answer

Usually it helps to talk calmly to the baby, maintain close contact, and use simple interactive games such as peek-a-boo and object tracking activities. Keeping a stable daily routine and responding consistently to the baby's signals also supports adaptation to new sensory and emotional experiences.

Question 4

What new skills appear after the third growth spurt?

Accepted Answer

Usually after the third growth spurt the baby develops longer visual attention, better tracking of moving objects, and early attempts at vocal interaction. They also begin recognizing familiar faces more clearly and responding more actively to voices, showing early social and communication development.
