What You Can Do to Help Your Child’s Development

Although your child is undergoing cancer treatment and may not feel energetic, it is still important to encourage movement, communication, and play as part of their daily routine. Here are some things you can do:

  • Place toys at different heights (such as on furniture or behind your child) around the room to encourage your child to move and change positions.
  • Once your child begins standing, help them practice walking by holding them at their tummy.
  • Provide toys that encourage your child to use both hands.
  • Provide toys that encourage your child to take objects out of a container and put them back inside.
