A 1-2 year old will point at pictures, scribble with a crayon, hold their own cup, remove their socks, feed themself using a spoon, and put a hat on their head. Before age 2 a toddler should be able to turn book pages, unzip a zipper, start coordinating movements with the wrist, fingers, and palm so they can unscrew a jar lid, use a cup with one hand, and unwrap paper from candy.
Some red flags are the following: child can't use pincer grasp, doesn't point at things, can't put things into containers, can't play using both hands, movements seem shaky or stiff, can't walk by 18 months, or loses skills he/she used to have. When these are seen in children from ages 1-2 it is an indicator that the toddler needs to see a doctor.
