In the first 12 months of your child’s life, your baby is learning and developing every day. During this time, they will reach many different milestones.

There are important times that you need to see a Child and Family Health Nurse to check that your child is developing well:  

  • 1-4 weeks 

  • 6-8 weeks 

  • 4 month immunisations 

  • 6 months 

  • 12 months 

  • 18 months 

  • 2 years, 3 years and 4 years

These milestones are reflected in how they play, learn, speak, behave and move. Your baby’s development can be looked at through five categories.  

  • Physical Development 

  • Social Development 

  • Emotional Development 

  • Cognitive Development 

  • Language Development 
     

It is important to remember that not every child will reach the same milestone at the same time.
