2 month old infant milestones

Developmental milestones for 2 month old infants

Developmental milestonesMay 18, 2025Dahlia Rimmon, MS, RDN2 min read

3 things that may have happened this month

  1. Oh, hello, smiley baby 👋 Your baby is smiling socially—on purpose! Those grins are their way of connecting, so keep chatting, singing, and making silly faces.
  2. Wait, was that a coo? Baby talk is here! Those sounds and gurgles are their first steps toward language. Talk back—they love the sound of your voice.
  3. Tiny kicks and punches 🥊 Movements are becoming more coordinated. Watch for stronger kicks during playtime and some epic arm flails.

Month 3 is coming, and it’s a game-changer

  1. More smiles and more fun 🤭 Your baby’s smiles will become more frequent and expressive, especially when they hear a familiar voice or see a familiar face.
  2. Exploring the world 🌎 Increased head control means they’ll start looking around more during tummy time and while being held upright.
  3. What’s that in their hand? 🧸 Grasping and holding toys is coming up next. Provide soft, safe objects for them to explore.

Proactive Tip: Try tummy time on different surfaces, like a soft mat or blanket. New textures and angles keep things interesting and help build strength!

Vaccines & well-child visits

Here’s what’s coming up in month 3 during your in-person pediatric visits:

The 2-month well-child visit:

Your pediatrician will:

  • Monitor your baby’s growth (weight, length, and head circumference).
  • Go over developmental milestones with you.
  • Answer any questions you have about sleep,feeding, or behavior.

Vaccines:

Your baby will receive their first round of vaccines, which include:

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

Tip: After vaccines, mild fussiness, a low-grade fever, or swelling at the injection site is normal. Keep infant acetaminophen on hand, and follow your pediatrician’s advice if needed.
