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.
Tree tobacco is a shrub that grows to be about 5 meters high. It was originally found in Argentina, but now grows worldwide. The leaves of tree tobacco contain a chemical called anabasine. This chemical makes tree tobacco leaves poisonous when taken by mouth. People apply tree tobacco to the skin for boils, fever, headache, pain, sore throat, and wounds. It has also been used as an insect repellant. How does it work? The leaves of tree tobacco contain a chemical called anabasine. Anabasine acts like a stimulant when taken at low doses and like a depressant when taken at high doses. This chemical also makes tree tobacco leaves poisonous when taken by mouth. But when tree tobacco is applied to the skin, it seems to help repel insects.
