The first month with a new baby in the house is undoubtedly thrilling for Mom and Dad… as well as the dog, neighbours, grandparents, and the mailman. But, even if the entire community is enthusiastic about the arrival of a baby, who could possibly be more excited than the baby himself?

Every sense that a baby possesses updates and adjusts to all the new things around them as they learn to live in the outside world for the first time. They must learn how to interact with this wonderful new world with all of their brand new body parts, which requires a lot of growth and development on their side.

The first month is one of the most transformative times in a baby’s life, and here are some of the most significant changes to anticipate.

Do any of these changes surprise you?

1. He’ll lose 10 percent of his body weight.

Your baby will lose weight rather than gain weight in the first week after birth, which can be concerning for many mothers. Bottle-fed newborns, on the other hand, can lose up to 10% of their birth weight without causing concern, and breastfed babies can lose up to 10% without causing concern.

2. But then he’ll gain an average of 8.8 ounces per week.

Your baby will develop gradually for the next three weeks after that initial decrease. During the first month, both they gain approximately 8.8 ounces per week, resulting in a total weight gain of roughly two and a half pounds.

3. She can see a foot further.

Babies are born partially blind; she will be so nearsighted that she will be unable to see anything but light and rough forms. However, in the first few weeks, her eyesight will improve to the point where she will be able to see objects from a distance of 10 to 12 inches.

4. He’ll start seeing colours.

Your baby will be able to discern between dark and light from the moment he is born, but it will take him around two weeks to see in colour. The first colour he’ll notice is red, and as his eyes develop, he’ll be able to see the rest of the rainbow as well.

5. She can start recognizing sounds

Even though your baby can hear before she is born, her hearing will not be fully developed until she is one month old. She’ll startle at loud noises and seem to recognise your voice, so you know she’s paying attention.

6. He’ll lose 2 hours of dream time.

Your infant will spend half of his sleep dreaming, which equates to eight hours of dreams per day if he sleeps a total of 16 hours each day. By the time he’s a month old, he’ll only be dreaming for around six hours each day… and by the time he’s an adult, he’ll only be dreaming for about 1.5 hours per night.

7. She’ll spend more time sleeping at night.

Even if it doesn’t feel like it yet, kids are well on their way to sleeping through the night by the time they’re a month old. Your kid will sleep 50% of the time at night after she is born. By the time she’s four weeks old, she’ll be closer to 60%.

8. She’ll eat twice as much.

It’s only natural: as your child develops, she’ll require more nourishment. Breastfed babies usually only consume 1.5 ounces of milk per feeding, but by the time she’s a month old, she’ll have consumed twice as much.

9. His head will grow an inch and a half.

Your baby’s head will grow at a higher rate in his first month than at any other period. By the time he’s a month old, it’ll have grown between an inch and two inches in size to accommodate his expanding brain.

10. He’ll figure out what he wants.

Your baby will find out exactly what he wants and how to get it in about a month. You’ll be able to know if he wants extra food or a diaper change in the first several weeks after he’s born because he’ll be making different cries for different problems.


  1. What milestones should a 1 month old have?

    Milestones in the Movement
    – Arm thrusts are jerky and trembling.
    – Brings hands within eye and tongue reach.
    – While lying on his stomach, moves his head from side to side.
    – If the head is not supported, it will flop backward.
    – Hands are clenched into fists.
    – Reflexive movements are very strong.

  2. What can babies do at 1 month?

    The majority of what babies do at one month is still due to reflexes. They aren’t considering the consequences of their acts. If you put anything in the palm of their hand, they’ll be sucking, swallowing, searching for milk, and clutching it (though they’ll usually keep their hands curled in tight tiny fists).

  3. What can babies see at 3 weeks?

    What can a newborn of three weeks see? Your baby’s vision is still limited to a few inches in front of them, and they can only distinguish black and white colours. 2 They, on the other hand, adore staring at their parents’ faces.

  4. At what age do babies smile?

    Your infant will have a “social” smile around the age of two months. That’s a smile that’s meant to get people’s attention. Babies form attachments to their caretakers about the same period, at 4 months of age.
