You will find him start testing your limits and discovering his own. Clashes between his wills and yours can be expected to occur. He is not intentionally trying to be mischievous, but simply trying to explore what he can do given his developmental capabilities. Remember that he counts on you to show him what is allowed and what is not, and will look to you frequently for reassurance and security. During this time, he will also show increasing signs of possessiveness with belongings and people close to him.1

Your baby will be able to:

  • Use walking as the usual means of mobility by around 18 months, although she may look unsteady on her legs

  • Drawing with crayon
  • Drinking water with a cup


Your children become able to speak and walk actively but their immune system is still weak. They are susceptible to several infectious diseases which can irreversibly damage their bodies. Therefore, it is important to bring your children to get booster vaccination for protection. At 18 months old, a booster dose will be given to protect your child against: diphtheria, tetanus, pertussis and polio, which is part of the series of vaccination your child has received at 2, 4 and 6 months respectively. There is also second dose of  Measles, Mumps, Rubella & Varicella (MMRV) Vaccine. Please take note children born between 1.1.2013 and 30.6.2018 receive MMRV vaccine in Primary 1. 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
