Movement and physical development

Normal development

  • Gets to a sitting position without help
  • Pulls up to stand, walks holding on to furniture (“cruising”)
  • May take a few steps without holding on
  • May stand alone

Possible challenges from treatment

  • Fewer chances to explore and have new experiences due to procedures and treatment. Tubes, drains, and lack of space can keep baby from moving and exploring normally.
  • Slower to learn large body movements, such as controlling head and upper body while sitting, crawling, and standing without help.
  • Slower to learn small movements, especially hand/eye coordination and holding things with thumb and finger.

Ways to help

  • If available, go to hospital infant playtime to help baby learn physical skills.
  • Ask for floor mat for movement and exploring.
  • Give toys with texture or musical toys to get baby interested in grabbing and moving objects.
  • Show baby “hide and seek” and other interactive games.
