Your Baby at 5 Months

Thinking Skills

  • Compares part of self to an object to differentiate himself from objects outside in the world -- for example, sucking on his thumb, then sucking on toy to feel the difference.
  • Learns to anticipate the result of his action -- hitting a dangling toy will make it swing.
  • Adds new elements to speech, such as yell, purr, blow "raspberries," and smacks lips. Mimics adult expressions and gestures as he babbles. Listens very intently to the human voice.
  • Develops rhythmic dialogue to take turns in "conversation."
  • May vocalize to draw his mother's attention when she is conversing with someone else.
  • Vision is improved to adjust focus to near and far. Developing depth perception. Sees in full color; likes orange, blue, green.
  • Watches and follows a familiar person leaving the room. Looks where you look.

Emotional Development

  • Indicates discomfort by pulling, poking or scratching at self.
  • Shows dislike by pushing things away from her.
  • Explores genitals by poking and pulling.
  • Enjoys loving exchange with caregiver during feeding time. May increase sucking time at breast or bottle.
  • Wakes quickly in the morning. May comfort herself by playing with a toy before you get her from the crib.
  • Hesitates and studies people outside her immediate family.
  • Has attention span of 10 to 15 minutes to play with toys alone.
  • Gives easily read behavioral cues. Extends hands, legs and body to you for "pick me up"; looks down to floor, squirms and fusses, meaning "put me down"; expressionless stare means "I'm bored"; cranky and nothing soothes means "I'm tired."
  • Likes to play peekaboo.
  • Learns to cough at will in order to attract attention.
