2 month old infant milestones
Developmental milestones for 2 month old infants

3 things that may have happened this month
- 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.
- 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.
- 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
- 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.
- Exploring the world 🌎 Increased head control means they’ll start looking around more during tummy time and while being held upright.
- 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.
