Toddler Development: Your 18 month old


Your 18 month old baby

Your baby will probably be able to…






Walk but he might stumble or need to sit down quickly

Want to explore

Want to try the stairs

Build with 3-4 bricks

Hold crayons with whole hand



Cognitive Development




Starting to learn trial and error, cause and effect

Follow simple instructions

Aware of the names of some objects



Language and


Say 20-50 simple words

Point and make noise to show what  he wants

May start to say no to everything



Emotional and
Social Development


Have a sense of self

Start expressing his needs and preferences

Enjoy the independence of walking, moving and playing

To do more on his own



Developmental Leaps

Each leap brings changes in behaviour, awareness, mood and sleep and your baby may seem unsettled and clingy


51-55 weeks – experimenting with play, actions and what comes next, 
very active with movement and exploring his surroundings


59-62 weeks – developing fears, emotions and wants to engage with people. 
Tantrums may begin as he pushes boundaries and want to do things his way


70-77 weeks – developing an understanding of time, of ownership, of empathy
