Baby Developmental Milestones: By 15 to 18 Months


Once your toddler is walking, it won't be long until they start to run. Make sure your yard is child-proofed and then get ready for the action! Play hide-and-seek and other chasing games to encourage physical activity.

May be scared of familiar objects like vacuum cleaners

Your toddler suddenly screams when you turn on the vacuum cleaner. What's up? It's not unusual for a toddler to be afraid of dogs, the dark, or loud noises, even from a familiar object. Comfort them, but let them know you're not afraid. Giving them a toy vacuum cleaner also may ease their fear.

May make a tower with 2 cubes

Picking up objects and seeing how they can be combined is a favorite pastime at this age. If your toddler can make a tower with 2 cubes, have them try making something with large building blocks of different shapes.

May say up to 10 words

Your baby soaks up everything you say, so now's a good time to give up baby talk. Point to objects -- at home, outside, in books -- and say their correct names so they learn them. By 18 months, they should say about 10 words.
