Eyes, month three

Last reviewed · 3 min read · 12 sources · Plain-text version

By 3 months, babies focus on faces and close objects and follow a moving one; colors come by 4 months. A mirror on the floor, and why your own vision changes are still urgent.

Two mothers on a living-room floor with their ten-week-old on a tummy-time blanket, the baby lifting their head toward a baby mirror propped in front, afternoon light.

Week 10 begins with the eyes: steadier now, and starting to go where your baby wants.

Heart

By 3 months, babies should be able to focus on faces and close objects and follow a moving object with their eyes. Occasional wandering or crossing should be going away by 2 to 3 months. By 4 months, babies see colors and shades better and often love circular patterns, one reason faces are so appealing (AAP).

Head

Eyes and hands are joining up: hands and eyes start working together around 2 months (AAP), and by about 8 weeks babies focus more easily on nearby faces (AOA). Color comes early: lab studies show 2-month-olds can already tell some colors apart (Teller, 1998). The AAP lists an unbreakable mirror among good toys around 4 months (AAP), and liking to look in a mirror is a 6-month milestone (CDC), so today is an introduction, not a test.

Body

Following with the eyes pulls the neck along. Watching you as you move is on the 2-month list (CDC), and holding the head steady when held is a 4-month milestone (CDC). On the tummy, something to look at is the reason to lift the head: set your face or toys in a circle around your baby to reach toward (AAP).

Try today

  1. One mother lies beside the baby so both faces appear in the small floor mirror, the baby staring at the reflection with mouth open, hands flat on the blanket.

    Mirror chats

    Time: 2 to 3 minutes, during tummy time or on your lap · Mirror chats in the guide

    1. Prop an unbreakable baby mirror in front of your baby during tummy time.

    2. Put your face next to theirs in the mirror and talk about what you see.

    3. Tilt the mirror slowly to one side and back, and watch whether their eyes follow.

    Make it work:

    Mirror play hasn't been studied; the point is a face to look at. Stop when your baby looks away or fusses, and if they get sleepy, lay them on their back in their own sleep space (Moon, AAP).

Watch for

  • Normal

    an eye that drifts now and then, going away by 2 to 3 months (AAP).

    Bring it up with your pediatrician

    if your baby's eyes still often cross or wander after 3 months (AAP).

  • Normal

    a long stare past you at the window.

    Bring it up with your pediatrician

    if your baby doesn't look at your face, and ask about developmental screening (CDC).

  • Normal

    breathing that speeds up with excitement and settles.

    Go to the ER now

    for any trouble breathing, including ribs pulling in with each breath or wheezing (AAP).

For you

The other mother sits on the edge of the bed with her glasses in one hand and her phone in the other, mid-call, her partner by the window holding the baby.

Your own vision changes are still urgent, ten weeks on. Changes in vision are on the CDC's list of urgent maternal warning signs, with a headache that won't go away or gets worse, and extreme swelling of your hands or face; seek care immediately, and tell the provider you were pregnant within the last year (CDC). The discharge instructions agree: swelling, a headache that won't go away, or vision changes can mean postpartum preeclampsia (MedlinePlus). Blurry patches, flashing lights, spots: not something to mention next week.

Tired eyes are different; if reading is harder than it was, say so at your postpartum visit.

If you're the partner: look at her eyes once today, and ask about the headache she hasn't mentioned.
