1 month old infant milestones

Infant 1 month developmental milestones, including vaccines and pediatrician visits

NewbornMay 1, 2025Dahlia Rimmon, MS, RDN2 min read

3 things that have happened in your baby's first month

  1. Whoa, they can see me đŸ€© Your baby’s vision is improving, and they can track faces, including your smile which is their new favorite thing.
  2. Why is my finger their new favorite toy? 🧾 Hello, grasp reflex! Those tiny fingers clinging to yours are a sign of their growing motor skills.
  3. Did they just flinch? đŸ€Ł The startle (or Moro) reflex is in full swing. Don’t worry—even though this reflex looks spastic, it’s their nervous system adjusting to the world outside the womb.

Vaccines & well-child visits

We’re here for you anytime, but staying on top of in-person care is essential too. Here’s what’s coming up:

The 1-Month Visit:

If you haven’t already had it, the 1-month well-child visit is a chance for your pediatrician to:

  • Monitor growth (weight, length, and head circumference).
  • Discuss feeding and sleep patterns.
  • Address any questions or concerns.

Vaccines:

At the 2-month visit, your baby will receive important vaccines, including:

  • DTaP (Diphtheria, Tetanus, and Pertussis)
  • Hib (Haemophilus influenzae type b)
  • IPV (Polio)
  • PCV13 (Pneumococcal)
  • Rotavirus

Tip from our pediatricians: After vaccines, mild fussiness or a low-grade fever is normal, but keep infant acetaminophen on hand in case you need it. If you have questions, reach out to our team 24/7 or your pediatrician if needed.

Here’s what’s coming in month 2

  1. Say cheese 😁 That first real social smile is just around the corner. Keep talking and making silly faces—it’s how babies learn connection.
  2. Head’s up 🆙 Your baby will hold their head up for longer stretches during tummy time, so it’s time to try new positions and entertainment to keep things interesting.
  3. Wait, was that a coo? đŸ„č Expect adorable babbles and coos as your little one begins to discover their voice. Talk back—they’re already learning conversation skills!

Tip: Create a milestone journal to capture all these moments so you can look back together in a few years.
