Baby Development By Day
|
Newborn (Day 1-14)
During the first two weeks of life, your baby is adjusting to life outside of the womb. They’re learning to breathe, eat, and sleep in their new environment. You’ll notice that your baby spends most of their time sleeping, waking up only to eat and have their diaper changed. Their movements will be jerky and uncoordinated, but they’ll gradually become more smooth and purposeful.
Week 2-4
By the end of the first month, your baby will start to become more alert and responsive to their surroundings. They’ll begin to recognize familiar faces and voices, and may even respond with a smile or coo. You may notice that they’re starting to develop a more regular feeding and sleeping schedule at this point.
Month 2-3
During this time, your baby’s motor skills will start to develop. They’ll begin to lift their head while lying on their stomach, and may even start to roll over. You’ll notice that they’re becoming more interested in their environment and may start to play with toys, even if it’s just grasping at them with their hands.
Month 4-6
Around this time, your baby’s personality will start to shine through. They’ll have distinct preferences and may even start to show a sense of humor. Their physical development will continue to progress, as they start to sit up on their own and may even start to crawl. You’ll also notice that they’re becoming more vocal and may start to babble and even say their first words!
Month 7-9
During this time, your baby’s mobility will really start to take off. They’ll be crawling, pulling themselves up to stand, and may even take their first steps. Their fine motor skills will also continue to develop, as they start to grasp small objects with their fingers and may even start to feed themselves.
Month 10-12
By the end of their first year, your baby will be a walking, talking little person! They’ll be speaking in sentences, playing with toys, and may even start to show signs of independence. They’ll also continue to develop their gross and fine motor skills, becoming more coordinated and dexterous with each passing day.

Frequently Asked Questions
How can I help my baby’s development?
The best thing you can do to help your baby’s development is to provide a safe, loving, and stimulating environment. Talk to your baby, read to them, play with them, and give them plenty of opportunities to explore their environment. Make sure they’re getting enough sleep, proper nutrition, and plenty of physical activity.
When should I be concerned about my baby’s development?
Every baby develops at their own pace, but if you notice that your baby is not meeting milestones or seems to be lagging behind in their development, it’s important to talk to your pediatrician. They can assess your baby’s development and provide any necessary interventions or referrals.
What are some red flags to look out for in my baby’s development?
Some red flags to look out for include a lack of responsiveness to their environment, not making eye contact, not showing interest in toys or other people, not babbling or making other vocalizations, not sitting up or moving around, or missing milestones altogether. Again, if you have concerns about your baby’s development, talk to your pediatrician.
What can I expect at my baby’s routine check-ups with the pediatrician?
At routine check-ups, your pediatrician will assess your baby’s growth and development, including their height, weight, and head circumference. They’ll also check their vision and hearing, and may ask you questions about their feeding, sleeping, and other habits. These check-ups are important for catching any potential issues early and ensuring that your baby is on track with their development.
How can I track my baby’s development at home?
There are several different ways you can track your baby’s development at home, including keeping a journal of their milestones, taking photos or videos of their progress, and using online resources to learn more about each stage of development. Just remember that every baby develops at their own pace, so don’t stress too much if your baby is not hitting milestones exactly on schedule.
