At 4 months old, your baby is becoming more aware of the world around them and their own abilities. They have likely doubled their birth weight and are becoming more alert and active each day. This month marks a significant time in their development and growth, both physically and mentally.

Physical Development

During this month, your baby will continue to grow and gain weight. They may reach a length of 26 to 29 inches and weigh between 13 and 15 pounds. They will also have improved head control and begin to sit up with support. Your baby may also begin to develop the ability to roll from their stomach to their back and vice versa, an important milestone in their physical development.

Cognitive Development

Your baby’s cognitive development is also rapidly advancing at this age. They will begin to show more interest in their surroundings, tracking objects and people with their eyes. They may also begin to recognize familiar faces and voices. In addition, they may start to develop a sense of object permanence, realizing that objects still exist even when they can’t see them.

Social and Emotional Development

At 4 months old, your baby will also begin to show more social and emotional development. They may start to form attachments to familiar people and may become more attached to a favorite toy or blanket. They will also begin to show their personality, with some babies being more easygoing and others more fussy. Your baby may also start to express their emotions more clearly, through crying, cooing, or laughing.

Tips for Supporting Your Baby’s Development

There are many ways you can support your baby’s development during this month. Encouraging playtime, reading to them, and interacting with them through singing and talking are all great ways to help their development. In addition, it’s important to provide a safe and supportive environment, with plenty of tummy time and opportunities for movement and exploration.
