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.
Affected trees may leak copious amounts of liquid out of their trunks or branches, discoloring the bark and dripping onto the surrounding ground. Bacterial wetwood occurs as after bacteria infect the wood of a tree.Bacteria can enter the wood through any wound in a trunk, limb or root. Once inside the tree, certain bacteria (called anaerobes) thrive in the low-oxygen environment there.ometimes the ooze kills the bark where it seeps out, and elms with wetwood often develop yellowed leaves and branch dieback as a result of the toxic liquid. On many infected trees, though, the foliage appears healthy, and wetwood often does not cause much damage to the rest of the tree.
