By 3 months infants do not engage in visual scanning. an infant's coordinated reaching and grabbing of an object is common. the ability to crawl has emerged. infants pay attention to facial expressions and smile more at smiling faces.

Explanation:

By regarding 3 months older, your baby’s crying ought to begin to fade.
Smiling sessions together with your baby can become more and more animated and joyful. once things get too emotionally intense for your baby, they're going to stop gazing at you, and that they can look for a number of moments. this can be referred to as gaze aversion, and it shows that your baby’s level of arousal is just too high. try and respect your baby’s would like for a possibility or a slower pace.
Your baby can still be fascinated by their voice. they're going to follow creating sounds whenever they're happy and content. they're going to relish imitating you and having you imitate them.
