3 Weeks Old Newborn Baby Development

Physical Development

At three weeks old, your baby is still very small, but they’re growing every day! By now, your baby should weigh around 8-10 pounds (3.6-4.5 kg) and measure about 20 inches (50 cm) in length. Their head circumference will also have grown by about 2 cm since birth.

One of the most exciting things about this stage of development is that your baby’s eyesight is improving. They can focus on objects that are about 10 inches (25 cm) away and can track slow-moving objects with their eyes. They can also distinguish between light and dark, and even recognize faces!

Your baby’s movements are also becoming more coordinated. They may start to move their arms and legs in a more purposeful way and are starting to gain more control over their head and neck movements. They may also start to grasp onto objects, such as your finger or a toy, and even bring their hands together.

Feeding

At three weeks old, most babies are still feeding every 2-3 hours, including overnight. You may notice that your baby is starting to develop a more regular feeding pattern and may be able to go slightly longer between feeds.

Breastfeeding is still the best option for your baby at this stage, as breast milk contains all the nutrients they need to grow and develop. If you’re struggling with breastfeeding, don’t hesitate to reach out to a lactation consultant for help.

Sleep

Newborns sleep a lot – typically around 16-17 hours per day. However, they may not sleep for long stretches at a time and may wake frequently for feeding or comfort.

It’s important to establish a consistent sleep routine for your baby, such as a bedtime routine that involves a bath, massage, and story time. This can help your baby learn to associate certain activities with sleep and may help them sleep for longer stretches at night.

Developmental Milestones

It’s important to remember that all babies develop at their own pace and may reach milestones at different times. However, here are some general milestones you can expect your baby to reach at around three weeks old:

• Lifting their head briefly while lying on their stomach
• Bringing their hands to their face
• Following slow-moving objects with their eyes
• Focusing on objects that are about 10 inches (25 cm) away
• Recognizing familiar faces
