Thanks for your question.
A two year old should be able to walk alone, pull toys behind him, start to learn to run, kick a ball, climb onto and down from furniture unassisted, dump things out of containers, point to pictures or objects, recognize familar faces, people and body parts, say single words and simple phrases, follow simple instructions, begin to sort things by shapes and sizes, immitate behavior of othes and begin to show defiant behavior (the word "no" comes into play).
By the time the child is 3 years old, a child should be able to climb well, walk up and down stairs alternating feet, run easily, pedal a tricycle, turn book pages, turn rotating handles, understand most sentences, understand physical relations like on, under and over, speak in 4 or 5 word sentences, know his name, age, and sex, uses pronouns (I, you, me), some plurals, and be understood by strngers.
The list is actually longer. Here are two sites with links to developmetnal milestones:
The milestones are the same for boys and girls. (Sex does influence the behavior of even little kids, but the milestones are the same.)
I noticed that you are in Malaysia. I think the milestones are the same for kids in Malysia as they in the US (and everywhere else).
