Your child becomes increasingly mobile. Being able to move about give her a sense of power and self-control for physical independence. At the same time, her sense of stranger anxiety also reaches its peak. You may find her eager to move about and to explore away on her own. Yet she may become distressed if she wanders out of your sight or you are too far away from her.

This is the time when your safety awareness is of definite importance. Make sure your home is already child-proofed. By providing a safe and interesting environment, you give her greater freedom such that she can make her own discoveries without much of your intervention.

Knowing when to guide a child and when to let her do things on her own is part of the art of parenting. The more opportunities you give her to discover, to test out and to solve problems, the stronger will be her capabilities, confidence and motivation to explore.

Your baby will be able to:1

  • Take objects out and put into containers
  • Sit well on the floor and can turn his body around to both sides without falling
  • Get from sitting to crawling or prone position
  • Explore objects in many different ways (shaking, banging, throwing and dropping)
  • Creep on tummy, or crawl on hands and knees, or shuffle on bottom
  • Pay increasing attention to speech
  • Understand " No "


Newborn babies are protected against several diseases, such as measles, mumps and rubella (MMR), because antibodies have been passed into them from their mothers. This immunity may last up to one year, which is why the MMR vaccine is given at 12 months. At this time, your baby is due to receive 3 vaccines for protection against three diseases; one for MMR, one for their final booster dose of pneumococcal and one dose for primary schedule against varicella.2

The Government will provide free or subsidised seasonal influenza vaccination to eligible children of age between 6 months and less than 12 years. Parents can arrange subsidised vaccination for their children in clinics of private doctors enrolled in the Vaccination Subsidy Scheme or Seasonal Influenza Vaccination School Outreach participated by their schools. Please consult your family doctor for further information.3
