2-4 Month Communication Milestones | Early Speech & Sound Development

Baby is becoming more familiar with the sounds around them and learning how to make their own! At 2-4 months, they’ll use vowel sounds and smiles to get your attention and show interest in sound-making toys. These 2-4 month communication milestones are important signs that Baby is growing typically and gaining the skills they'll need for future development.

Tracking these milestones helps you support healthy communication development and notice if Baby needs a little extra help.

Baby should meet these communication milestones by 4 months:

✅ Makes different vowel sounds, e.g. eee, ooo, ahh, uh
✅ Turns head towards sound or voice
✅ Notices toys that make sounds
✅ Uses smiles, sounds, or movement to get attention
