Your Baby at 3 Months

Here are growth and development patterns of a child at three months. Each step listed represents an average of a time span of six to sometimes 12 weeks that is considered within the normal range for that behavior. Don't be concerned if your child is not doing something listed here. Each baby develops at her own pace.

Body Movement

  • Lifts head when lying on tummy. When held on adult's chest, will push away and look over your shoulder. Turns head from side to side while on stomach and propped up on forearms.
  • When on stomach, with weight on elbows and forearms, arms can lift chest. Legs remain flexed when lying on stomach.
  • Sits erect when supported at the hips.
  • Arm movements are more purposeful. Enjoys moving arms and legs vigorously when lying on back, sometimes symmetrically or in bicycle motion.

Eye-Hand Coordination

  • Eyes can follow a moving object held about six inches above her face vertically and in a circular pattern. She can see objects 15 to 20 feet away.
  • Hands open most of the time. Voluntarily shakes and holds a rattle. Grabs onto your clothing and hair.
  • Looks at her hand held in front of her face. Enjoys watching her fingers move. Grabs one hand with other one. Sucks on fist.
  • Swings at and reaches for dangling objects. Likes to feel different textures of objects.
  • Explores her own face, eyes and mouth with her hand.
  • Loses interest in mobiles if they're beyond her reach.
