At 18 months old, babies are starting to become more interested in the world around them. They may be curious about other people and want to explore new things. This is a normal part of development, and there are many ways parents can encourage their child's interests.
Some 18 month olds may be interested in:
-Playing with other children or adults
-Exploring new places
-Touching and feeling different textures
-Putting things in their mouth (tasting/mouthing)
-Imitating others, such as adults or older siblings
