What developmental milestone is expected in an infant at 3 months of age?

1. Raising their chest when lying on their stomach

2. Following objects 180 degrees with their eyes

3. Beginning to babble

4. All of the above

The correct answer is: All of the above

At 3 months of age, infants typically exhibit several key developmental milestones that relate to their physical, visual, and verbal development. One important milestone is the ability to raise their chest while lying on their stomach. This behavior indicates developing muscle strength and is part of the progression toward crawling. Additionally, the capability of following objects with their eyes has progressed significantly by this age. Infants at this stage can usually follow moving objects through a range of about 180 degrees, showing improvement in their visual tracking and coordination. Verbal development is also notable, as many infants begin to coo and might start to babble by around 3 months. This reflects their growing ability to communicate and initiate social interaction. Therefore, all of these milestones are expected and welcomed indicators of healthy development at the 3-month mark. Recognizing these milestones allows caregivers and healthcare providers to monitor growth and development effectively.
