While keeping in mind that every child is different, there are some physical milestones children generally reach by age 2. If your child is not walking alone by age 2, speak with your pediatrician. Most children also pull toys while walking, can carry toys while walking, are running, can stand on tiptoe, kick a ball, and climb. If you have stairs, your child is likely walking up and down the stairs while holding the railing or someone's hand. By age 2, children have developed the fine motor control to draw scribbles, dump and pour out the contents of a container, and stack blocks.
