Baby First 3 Months Development

The first three months of a baby’s life is a critical time for development. During these months, babies go through a rapid phase of growth and development, becoming more aware of their surroundings, and gaining new skills at a remarkable rate. As a parent, it’s essential to know what to expect during this time, so you can support your baby’s development and help them reach their full potential.

Physical Development

During the first three months, your baby’s physical development will be rapid. They will gain weight and length quickly, with most babies doubling their birth weight by two months old. They will also start to develop better control over their movements, such as lifting their head and kicking their legs. By three months old, most babies can support their head and chest when lying on their stomachs and can push up with their arms.

Cognitive Development

Cognitive development is another crucial area of development during the first three months. At birth, babies’ brains are wired to learn and adapt to their environment, and they will quickly start to recognize familiar faces and voices. They will also start to learn cause and effect, such as realizing that crying leads to someone coming to comfort them. By two months old, babies will start to track moving objects with their eyes and respond to familiar sounds.

Social and Emotional Development

Babies are social creatures, and they crave human interaction. During the first three months, they will start to develop social and emotional bonds with their caregivers. They will start to smile and coo in response to familiar faces and voices and may even start to babble. They will also start to show preferences for certain people and may become upset when separated from their primary caregiver.

Sleep and feeding are also critical aspects of a baby’s development during the first three months. Most babies will sleep for around 16-17 hours a day, with frequent wake-ups for feeding. It’s important to establish a consistent feeding and sleeping routine to help babies feel secure and comfortable. During this time, most babies will feed every 2-3 hours, with each feeding lasting around 20-30 minutes.


The first three months of a baby’s life are a period of significant growth and development. As a parent, it’s essential to support your baby’s development by providing a safe and nurturing environment and responding to their needs promptly.
