Babies this age can focus on shapes that are close by, but see distant objects as blurry because they are nearsighted. As babies grow, eyesight improves. By the end of 3 months, they can follow a moving object, are more interested in shapes and patterns, and can spot familiar faces, even at a distance. Human faces are one of their favorite things to look at, especially their own or a parent's face.
Watch out for cracks, cankers, and holes. Cankers are lesions on the branches and trunk of the tree, often circular or oval, with a sunken center and raised edges. Deep splits through the bark are also signs of possible tree failure. Be on the lookout for sap seepage, whether from a wound or other area of the tree. Sap seepage can be an indication of a bacterial infection within the tree, or damage being done to the tree by insects or birds.
Symptoms And Signs. 1  Light or dark streaks on the bark originate at a crack or wound and run vertically down the trunk. 2  Slimy, sometimes foul smelling liquid bubbles out of the tree and runs down the trunk.  Heartwood deep in the interior of the tree is much darker than surrounding sapwood.
